A biologist conducting research in a biotechnology laboratory

Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms and parts thereof for products and services.[1] Specialists in the field are known as biotechnologists.

The term biotechnology was first used by Károly Ereky in 1919[2] to refer to the production of products from raw materials with the aid of living organisms. The core principle of biotechnology involves harnessing biological systems and organisms, such as bacteria, yeast, and plants, to perform specific tasks or produce valuable substances.

Biotechnology had a significant impact on many areas of society, from medicine to agriculture to environmental science. One of the key techniques used in biotechnology is genetic engineering, which allows scientists to modify the genetic makeup of organisms to achieve desired outcomes. This can involve inserting genes from one organism into another, and consequently, create new traits or modifying existing ones.[3]

Other important techniques used in biotechnology include tissue culture, which allows researchers to grow cells and tissues in the lab for research and medical purposes, and fermentation, which is used to produce a wide range of products such as beer, wine, and cheese.

The applications of biotechnology are diverse and have led to the development of products like life-saving drugs, biofuels, genetically modified crops, and innovative materials.[4] It has also been used to address environmental challenges, such as developing biodegradable plastics and using microorganisms to clean up contaminated sites.

Biotechnology is a rapidly evolving field with significant potential to address pressing global challenges and improve the quality of life for people around the world; however, despite its numerous benefits, it also poses ethical and societal challenges, such as questions around genetic modification and intellectual property rights. As a result, there is ongoing debate and regulation surrounding the use and application of biotechnology in various industries and fields.

Applications

Biotechnology encompasses a wide range of procedures for modifying living organisms for human purposes, going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering, as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms, such as pharmaceuticals, crops, and livestock.[6] As per the European Federation of Biotechnology, biotechnology is the integration of natural science and organisms, cells, parts thereof, and molecular analogues for products and services.[7] Biotechnology is based on the basic biological sciences (e.g., molecular biology, biochemistry, cell biology, embryology, genetics, microbiology) and conversely provides methods to support and perform basic research in biology.[citation needed]

Principles of Tissue Engineering

Biotechnology is the research and development in the laboratory using bioinformatics for exploration, extraction, exploitation, and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned (reproduced by biosynthesis, for example), forecasted, formulated, developed, manufactured, and marketed for the purpose of sustainable operations (for the return from bottomless initial investment on R & D) and gaining durable patents rights (for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects or safety concerns by using the products).[8][9][10] The utilization of biological processes, organisms or systems to produce products that are anticipated to improve human lives is termed biotechnology.[11]

By contrast, bioengineering is generally thought of as a related field that more heavily emphasizes higher systems approaches (not necessarily the altering or using of biological materials directly) for interfacing with and utilizing living things. Bioengineering is the application of the principles of engineering and natural sciences to tissues, cells, and molecules. This can be considered as the use of knowledge from working with and manipulating biology to achieve a result that can improve functions in plants and animals.[12] Relatedly, biomedical engineering is an overlapping field that often draws upon and applies biotechnology (by various definitions), especially in certain sub-fields of biomedical or chemical engineering such as tissue engineering, biopharmaceutical engineering, and genetic engineering.[citation needed]

History

[edit]
Main article: History of biotechnology
Brewing was an early application of biotechnology.

Many forms of human-derived agriculture fit the broad definition of "utilizing a biotechnological system to make products". The cultivation of plants may be viewed as the earliest biotechnological enterprise.[citation needed]

Agriculture has been theorized to have become the dominant way of producing food since the Neolithic Revolution. Through early biotechnology, the earliest farmers selected and bred the best-suited crops (e.g., those with the highest yields) to produce enough food to support a growing population. As crops and fields became increasingly large and difficult to maintain, it was discovered that specific organisms and their by-products could effectively fertilize, restore nitrogen, and control pests. Throughout the history of agriculture, farmers have inadvertently altered the genetics of their crops through introducing them to new environments and breeding them with other plants — one of the first forms of biotechnology.[clarification needed]

These processes also were included in early fermentation of beer.[13] These processes were introduced in early Mesopotamia, Egypt, China and India, and still use the same basic biological methods. In brewing, malted grains (containing enzymes) convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in the grains broke down into alcohols, such as ethanol. Later, other cultures produced the process of lactic acid fermentation, which produced other preserved foods, such as soy sauce. Fermentation was also used in this time period to produce leavened bread. Although the process of fermentation was not fully understood until Louis Pasteur's work in 1857, it is still the first use of biotechnology to convert a food source into another form.[citation needed]

Before the time of Charles Darwin's work and life, animal and plant scientists had already used selective breeding. Darwin added to that body of work with his scientific observations about the ability of science to change species. These accounts contributed to Darwin's theory of natural selection.[14]

For thousands of years, humans have used selective breeding to improve the production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics. For example, this technique was used with corn to produce the largest and sweetest crops.[15]

In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. In 1917, Chaim Weizmann first used a pure microbiological culture in an industrial process, that of manufacturing corn starch using Clostridium acetobutylicum, to produce acetone, which the United Kingdom desperately needed to manufacture explosives during World War I.[16]

Biotechnology has also led to the development of antibiotics. In 1928, Alexander Fleming discovered the mold Penicillium. His work led to the purification of the antibiotic formed by the mold by Howard Florey, Ernst Boris Chain and Norman Heatley – to form what we today know as penicillin. In 1940, penicillin became available for medicinal use to treat bacterial infections in humans.[15]

The field of modern biotechnology is generally thought of as having been born in 1971 when Paul Berg's (Stanford) experiments in gene splicing had early success. Herbert W. Boyer (Univ. Calif. at San Francisco) and Stanley N. Cohen (Stanford) significantly advanced the new technology in 1972 by transferring genetic material into a bacterium, such that the imported material would be reproduced. The commercial viability of a biotechnology industry was significantly expanded on June 16, 1980, when the United States Supreme Court ruled that a genetically modified microorganism could be patented in the case of Diamond v. Chakrabarty.[17] Indian-born Ananda Chakrabarty, working for General Electric, had modified a bacterium (of the genus Pseudomonas) capable of breaking down crude oil, which he proposed to use in treating oil spills. (Chakrabarty's work did not involve gene manipulation but rather the transfer of entire organelles between strains of the Pseudomonas bacterium).[citation needed]

The MOSFET invented at Bell Labs between 1955 and 1960,[18][19][20][21][22][23] Two years later, Leland C. Clark and Champ Lyons invented the first biosensor in 1962.[24][25] Biosensor MOSFETs were later developed, and they have since been widely used to measure physical, chemical, biological and environmental parameters.[26] The first BioFET was the ion-sensitive field-effect transistor (ISFET), invented by Piet Bergveld in 1970.[27][28] It is a special type of MOSFET,[26] where the metal gate is replaced by an ion-sensitive membrane, electrolyte solution and reference electrode.[29] The ISFET is widely used in biomedical applications, such as the detection of DNA hybridization, biomarker detection from blood, antibody detection, glucose measurement, pH sensing, and genetic technology.[29]

By the mid-1980s, other BioFETs had been developed, including the gas sensor FET (GASFET), pressure sensor FET (PRESSFET), chemical field-effect transistor (ChemFET), reference ISFET (REFET), enzyme-modified FET (ENFET) and immunologically modified FET (IMFET).[26] By the early 2000s, BioFETs such as the DNA field-effect transistor (DNAFET), gene-modified FET (GenFET) and cell-potential BioFET (CPFET) had been developed.[29]

A factor influencing the biotechnology sector's success is improved intellectual property rights legislation—and enforcement—worldwide, as well as strengthened demand for medical and pharmaceutical products.[30]

Rising demand for biofuels is expected to be good news for the biotechnology sector, with the Department of Energy estimating ethanol usage could reduce U.S. petroleum-derived fuel consumption by up to 30% by 2030. The biotechnology sector has allowed the U.S. farming industry to rapidly increase its supply of corn and soybeans—the main inputs into biofuels—by developing genetically modified seeds that resist pests and drought. By increasing farm productivity, biotechnology boosts biofuel production.[31]

Examples

[edit]
Further information: Outline of biotechnology

Biotechnology has applications in four major industrial areas, including health care (medical), crop production and agriculture, non-food (industrial) uses of crops and other products (e.g., biodegradable plastics, vegetable oil, biofuels), and environmental uses.[32]

For example, one application of biotechnology is the directed use of microorganisms for the manufacture of organic products (examples include beer and milk products). Another example is using naturally present bacteria by the mining industry in bioleaching.[33] Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and also to produce biological weapons.

A series of derived terms have been coined to identify several branches of biotechnology, for example:

  • Bioinformatics (or "gold biotechnology") is an interdisciplinary field that addresses biological problems using computational techniques, and makes the rapid organization as well as analysis of biological data possible. The field may also be referred to as computational biology, and can be defined as, "conceptualizing biology in terms of molecules and then applying informatics techniques to understand and organize the information associated with these molecules, on a large scale".[34] Bioinformatics plays a key role in various areas, such as functional genomics, structural genomics, and proteomics, and forms a key component in the biotechnology and pharmaceutical sector.[35]
  • Blue biotechnology is based on the exploitation of sea resources to create products and industrial applications.[36] This branch of biotechnology is the most used for the industries of refining and combustion principally on the production of bio-oils with photosynthetic micro-algae.[36][37]
  • Green biotechnology is biotechnology applied to agricultural processes. An example would be the selection and domestication of plants via micropropagation. Another example is the designing of transgenic plants to grow under specific environments in the presence (or absence) of chemicals. One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture. An example of this is the engineering of a plant to express a pesticide, thereby ending the need of external application of pesticides. An example of this would be Bt corn. Whether or not green biotechnology products such as this are ultimately more environmentally friendly is a topic of considerable debate.[36] It is commonly considered as the next phase of green revolution, which can be seen as a platform to eradicate world hunger by using technologies which enable the production of more fertile and resistant, towards biotic and abiotic stress, plants and ensures application of environmentally friendly fertilizers and the use of biopesticides, it is mainly focused on the development of agriculture.[36] On the other hand, some of the uses of green biotechnology involve microorganisms to clean and reduce waste.[38][36]
  • Red biotechnology is the use of biotechnology in the medical and pharmaceutical industries, and health preservation.[36] This branch involves the production of vaccines and antibiotics, regenerative therapies, creation of artificial organs and new diagnostics of diseases.[36] As well as the development of hormones, stem cells, antibodies, siRNA and diagnostic tests.[36]
  • White biotechnology, also known as industrial biotechnology, is biotechnology applied to industrial processes. An example is the designing of an organism to produce a useful chemical. Another example is the using of enzymes as industrial catalysts to either produce valuable chemicals or destroy hazardous/polluting chemicals. White biotechnology tends to consume less in resources than traditional processes used to produce industrial goods.[39][40]
  • Yellow biotechnology refers to the use of biotechnology in food production (food industry), for example in making wine (winemaking), cheese (cheesemaking), and beer (brewing) by fermentation.[36] It has also been used to refer to biotechnology applied to insects. This includes biotechnology-based approaches for the control of harmful insects, the characterisation and utilisation of active ingredients or genes of insects for research, or application in agriculture and medicine and various other approaches.[41]
  • Gray biotechnology is dedicated to environmental applications, and focused on the maintenance of biodiversity and the remotion of pollutants.[36]
  • Brown biotechnology is related to the management of arid lands and deserts. One application is the creation of enhanced seeds that resist extreme environmental conditions of arid regions, which is related to the innovation, creation of agriculture techniques and management of resources.[36]
  • Violet biotechnology is related to law, ethical and philosophical issues around biotechnology.[36]
  • Microbial biotechnology has been proposed for the rapidly emerging area of biotechnology applications in space and microgravity (space bioeconomy)[42]
  • Dark biotechnology is the color associated with bioterrorism or biological weapons and biowarfare which uses microorganisms, and toxins to cause diseases and death in humans, livestock and crops.[43][36]

Medicine

[edit]

In medicine, modern biotechnology has many applications in areas such as pharmaceutical drug discoveries and production, pharmacogenomics, and genetic testing (or genetic screening). In 2021, nearly 40% of the total company value of pharmaceutical biotech companies worldwide were active in Oncology with Neurology and Rare Diseases being the other two big applications.[44]

Pharmacogenomics (a combination of pharmacology and genomics) is the technology that analyses how genetic makeup affects an individual's response to drugs.[45] Researchers in the field investigate the influence of genetic variation on drug responses in patients by correlating gene expression or single-nucleotide polymorphisms with a drug's efficacy or toxicity.[46] The purpose of pharmacogenomics is to develop rational means to optimize drug therapy, with respect to the patients' genotype, to ensure maximum efficacy with minimal adverse effects.[47] Such approaches promise the advent of "personalized medicine"; in which drugs and drug combinations are optimized for each individual's unique genetic makeup.[48][49]

Biotechnology has contributed to the discovery and manufacturing of traditional small molecule pharmaceutical drugs as well as drugs that are the product of biotechnology – biopharmaceutics. Modern biotechnology can be used to manufacture existing medicines relatively easily and cheaply. The first genetically engineered products were medicines designed to treat human diseases. To cite one example, in 1978 Genentech developed synthetic humanized insulin by joining its gene with a plasmid vector inserted into the bacterium Escherichia coli. Insulin, widely used for the treatment of diabetes, was previously extracted from the pancreas of abattoir animals (cattle or pigs). The genetically engineered bacteria are able to produce large quantities of synthetic human insulin at relatively low cost.[50][51] Biotechnology has also enabled emerging therapeutics like gene therapy. The application of biotechnology to basic science (for example through the Human Genome Project) has also dramatically improved our understanding of biology and as our scientific knowledge of normal and disease biology has increased, our ability to develop new medicines to treat previously untreatable diseases has increased as well.[51]

Genetic testing allows the genetic diagnosis of vulnerabilities to inherited diseases, and can also be used to determine a child's parentage (genetic mother and father) or in general a person's ancestry. In addition to studying chromosomes to the level of individual genes, genetic testing in a broader sense includes biochemical tests for the possible presence of genetic diseases, or mutant forms of genes associated with increased risk of developing genetic disorders. Genetic testing identifies changes in chromosomes, genes, or proteins.[52] Most of the time, testing is used to find changes that are associated with inherited disorders. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder. As of 2011 several hundred genetic tests were in use.[53][54] Since genetic testing may open up ethical or psychological problems, genetic testing is often accompanied by genetic counseling.

Agriculture

[edit]

Genetically modified crops ("GM crops", or "biotech crops") are plants used in agriculture, the DNA of which has been modified with genetic engineering techniques. In most cases, the main aim is to introduce a new trait that does not occur naturally in the species. Biotechnology firms can contribute to future food security by improving the nutrition and viability of urban agriculture. Furthermore, the protection of intellectual property rights encourages private sector investment in agrobiotechnology.[55]

Examples in food crops include resistance to certain pests,[56] diseases,[57] stressful environmental conditions,[58] resistance to chemical treatments (e.g. resistance to a herbicide[59]), reduction of spoilage,[60] or improving the nutrient profile of the crop.[61] Examples in non-food crops include production of pharmaceutical agents,[62] biofuels,[63] and other industrially useful goods,[64] as well as for bioremediation.[65][66]

Farmers have widely adopted GM technology. Between 1996 and 2011, the total surface area of land cultivated with GM crops had increased by a factor of 94, from 17,000 to 1,600,000 square kilometers (4,200,000 to 395,400,000 acres).[67] 10% of the world's crop lands were planted with GM crops in 2010.[67] As of 2011, 11 different transgenic crops were grown commercially on 395 million acres (160 million hectares) in 29 countries such as the US, Brazil, Argentina, India, Canada, China, Paraguay, Pakistan, South Africa, Uruguay, Bolivia, Australia, Philippines, Myanmar, Burkina Faso, Mexico, and Spain.[67]

Genetically modified foods are foods produced from organisms that have had specific changes introduced into their DNA with the methods of genetic engineering. These techniques have allowed for the introduction of new crop traits as well as a far greater control over a food's genetic structure than previously afforded by methods such as selective breeding and mutation breeding.[68] Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed ripening tomato.[69] To date most genetic modification of foods have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil. These have been engineered for resistance to pathogens and herbicides and better nutrient profiles. GM livestock have also been experimentally developed; in November 2013 none were available on the market,[70] but in 2015 the FDA approved the first GM salmon for commercial production and consumption.[71]

There is a scientific consensus[72][73][74][75] that currently available food derived from GM crops poses no greater risk to human health than conventional food,[76][77][78][79][80] but that each GM food needs to be tested on a case-by-case basis before introduction.[81][82][83] Nonetheless, members of the public are much less likely than scientists to perceive GM foods as safe.[84][85][86][87] The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation.[88][89][90][91]

GM crops also provide a number of ecological benefits, if not used in excess.[92] Insect-resistant crops have proven to lower pesticide usage, therefore reducing the environmental impact of pesticides as a whole.[93] However, opponents have objected to GM crops per se on several grounds, including environmental concerns, whether food produced from GM crops is safe, whether GM crops are needed to address the world's food needs, and economic concerns raised by the fact these organisms are subject to intellectual property law.

Biotechnology has several applications in the realm of food security. Crops like Golden rice are engineered to have higher nutritional content, and there is potential for food products with longer shelf lives.[94] Though not a form of agricultural biotechnology, vaccines can help prevent diseases found in animal agriculture. Additionally, agricultural biotechnology can expedite breeding processes in order to yield faster results and provide greater quantities of food.[95] Transgenic biofortification in cereals has been considered as a promising method to combat malnutrition in India and other countries.[96]

Industrial

[edit]

Industrial biotechnology (known mainly in Europe as white biotechnology) is the application of biotechnology for industrial purposes, including industrial fermentation. It includes the practice of using cells such as microorganisms, or components of cells like enzymes, to generate industrially useful products in sectors such as chemicals, food and feed, detergents, paper and pulp, textiles and biofuels.[97] In the current decades, significant progress has been done in creating genetically modified organisms (GMOs) that enhance the diversity of applications and economical viability of industrial biotechnology. By using renewable raw materials to produce a variety of chemicals and fuels, industrial biotechnology is actively advancing towards lowering greenhouse gas emissions and moving away from a petrochemical-based economy.[98]

Synthetic biology is considered one of the essential cornerstones in industrial biotechnology due to its financial and sustainable contribution to the manufacturing sector. Jointly biotechnology and synthetic biology play a crucial role in generating cost-effective products with nature-friendly features by using bio-based production instead of fossil-based.[99] Synthetic biology can be used to engineer model microorganisms, such as Escherichia coli, by genome editing tools to enhance their ability to produce bio-based products, such as bioproduction of medicines and biofuels.[100] For instance, E. coli and Saccharomyces cerevisiae in a consortium could be used as industrial microbes to produce precursors of the chemotherapeutic agent paclitaxel by applying the metabolic engineering in a co-culture approach to exploit the benefits from the two microbes.[101]

Another example of synthetic biology applications in industrial biotechnology is the re-engineering of the metabolic pathways of E. coli by CRISPR and CRISPRi systems toward the production of a chemical known as 1,4-butanediol, which is used in fiber manufacturing. In order to produce 1,4-butanediol, the authors alter the metabolic regulation of the Escherichia coli by CRISPR to induce point mutation in the gltA gene, knockout of the sad gene, and knock-in six genes (cat1, sucD, 4hbd, cat2, bld, and bdh). Whereas CRISPRi system used to knockdown the three competing genes (gabD, ybgC, and tesB) that affect the biosynthesis pathway of 1,4-butanediol. Consequently, the yield of 1,4-butanediol significantly increased from 0.9 to 1.8 g/L.[102]

Environmental

[edit]

Environmental biotechnology includes various disciplines that play an essential role in reducing environmental waste and providing environmentally safe processes, such as biofiltration and biodegradation.[103][104] The environment can be affected by biotechnologies, both positively and adversely. Vallero and others have argued that the difference between beneficial biotechnology (e.g., bioremediation is to clean up an oil spill or hazard chemical leak) versus the adverse effects stemming from biotechnological enterprises (e.g., flow of genetic material from transgenic organisms into wild strains) can be seen as applications and implications, respectively.[105] Cleaning up environmental wastes is an example of an application of environmental biotechnology; whereas loss of biodiversity or loss of containment of a harmful microbe are examples of environmental implications of biotechnology.[citation needed]

Many cities have installed CityTrees, which use biotechnology to filter pollutants from urban atmospheres.[106]

Regulation

[edit]
Main articles: Regulation of genetic engineering and Regulation of the release of genetic modified organisms

The regulation of genetic engineering concerns approaches taken by governments to assess and manage the risks associated with the use of genetic engineering technology, and the development and release of genetically modified organisms (GMO), including genetically modified crops and genetically modified fish. There are differences in the regulation of GMOs between countries, with some of the most marked differences occurring between the US and Europe.[107][108] Regulation varies in a given country depending on the intended use of the products of the genetic engineering. For example, a crop not intended for food use is generally not reviewed by authorities responsible for food safety.[109] The European Union differentiates between approval for cultivation within the EU and approval for import and processing. While only a few GMOs have been approved for cultivation in the EU a number of GMOs have been approved for import and processing.[110] The cultivation of GMOs has triggered a debate about the coexistence of GM and non-GM crops. Depending on the coexistence regulations, incentives for the cultivation of GM crops differ.[111]

Database for the GMOs used in the EU

[edit]

The EUginius (European GMO Initiative for a Unified Database System) database is intended to help companies, interested private users and competent authorities to find precise information on the presence, detection and identification of GMOs used in the European Union. The information is provided in English.[112]

Learning

[edit]
Central New York Biotech Accelerator, Upstate Medical University

In 1988, after prompting from the United States Congress, the National Institute of General Medical Sciences (National Institutes of Health) (NIGMS) instituted a funding mechanism for biotechnology training. Universities nationwide compete for these funds to establish Biotechnology Training Programs (BTPs). Each successful application is generally funded for five years then must be competitively renewed. Graduate students in turn compete for acceptance into a BTP; if accepted, then stipend, tuition and health insurance support are provided for two or three years during the course of their PhD thesis work. Nineteen institutions offer NIGMS supported BTPs.[113] Biotechnology training is also offered at the undergraduate level and in community colleges.[citation needed]

Fundamentals

Definition and Scope

Biotechnology is defined as the application of science and technology to living organisms, as well as parts, products, and models thereof, to alter living or non-living materials for the production of knowledge, goods, and services. This formulation, established by the in , emphasizes the manipulation of biological systems for practical outcomes across diverse sectors. The field integrates principles from , chemistry, , and to harness cellular and biomolecular processes. The term "biotechnology" was coined in 1919 by Hungarian engineer , who used it to describe the production of products from raw materials with the aid of living organisms, initially in the context of agricultural advancements like intensified . envisioned biotechnology as a systematic approach to leveraging biological agents for industrial-scale transformation, distinguishing it from ad hoc traditional practices such as .

While early biotechnology relied on and microbial dating back millennia, modern biotechnology, post-1970s, focuses on and for precise molecular interventions. This breadth positions biotechnology as a foundational addressing global challenges in , , and resource efficiency, though ethical and regulatory considerations delimit its implementation in areas like human germline editing.

Core Principles

Biotechnology is grounded in the manipulation of biological systems to achieve practical outcomes, primarily through two interconnected principles: genetic engineering and bioprocess engineering. Genetic engineering entails the deliberate alteration of an organism's genetic material to confer desired traits or synthesize specific biomolecules, relying on recombinant DNA technology. For context, the DNA within a single human cell, if stretched out, measures approximately 2 meters in length. This involves isolating a target gene, incorporating it into a vector like a plasmid using restriction enzymes to cut DNA and ligase to seal fragments, and introducing the construct into a compatible host cell, such as bacteria or yeast, for replication and expression. The efficacy of genetic engineering stems from the central dogma of molecular biology, which describes the flow of genetic information from DNA via transcription to messenger RNA and translation into proteins, allowing precise interventions at the genomic level. Host organisms are selected for their ability to maintain the recombinant DNA through cell division and express the foreign gene phenotypically, as exemplified by the production of human insulin in Escherichia coli since the late 1970s. Selectable markers, such as antibiotic resistance genes, ensure only transformed cells survive, facilitating identification and propagation. Bioprocess engineering complements genetic manipulation by enabling scalable production of biotechnological outputs. This principle involves cultivating engineered or natural organisms in controlled environments, such as stirred-tank bioreactors, under optimized conditions of , , oxygen levels, and nutrients to maximize yield. Sterility is paramount to prevent contamination, with steps like , , and purifying products such as enzymes, vaccines, or monoclonal antibodies. technology, a foundational , harnesses for metabolite production, as in penicillin synthesis using Penicillium fungi scaled industrially since the 1940s. These principles integrate —where enzymes and cellular machinery perform reactions with —with scalability, drawing on the inherent capabilities of for efficient, targeted unattainable by purely chemical means. Advances like CRISPR-Cas9 have refined since 2012, enhancing precision in gene editing while bioprocess innovations, including single-use bioreactors, improve efficiency and reduce costs in industrial applications.

Key Techniques and Tools

Recombinant DNA technology, pioneered in 1972 by and further developed by Stanley Cohen and , enables the combination of genetic material from different sources using restriction endonucleases to cut DNA at specific sequences and to join fragments, often inserting them into vectors for propagation in host cells like . This technique forms the basis for producing recombinant proteins, such as human insulin first achieved in 1978 by . The (PCR), invented in 1983 by at , amplifies targeted DNA segments exponentially through repeated cycles of thermal denaturation, primer annealing, and DNA polymerase extension, typically using thermostable * isolated from . By 1985, refinements allowed automated cycling, revolutionizing diagnostics, forensics, and ; a single PCR run can generate billions of copies from nanogram quantities of starting material in under two hours. CRISPR-Cas9 genome editing, adapted from the bacterial and demonstrated for eukaryotic use in 2012 by , , and colleagues, employs a single-guide (sgRNA) to direct the endonuclease to cleave DNA at precise loci, inducing double-strand breaks repaired via or homology-directed repair for insertions, deletions, or substitutions. This programmable tool offers higher specificity and efficiency than prior methods like zinc-finger nucleases, enabling applications from crop improvement to therapeutic gene correction, though off-target effects remain a challenge requiring variants like high-fidelity . Bioreactors, essential for industrial-scale bioprocessing, maintain optimal conditions—such as 6-7, temperatures of 30-37°C, and dissolved oxygen levels via sparging and agitation—for microbial or mammalian , yielding products like antibiotics or through batch, fed-batch, or continuous modes. Stirred-tank designs predominate, scaling from lab volumes of liters to commercial capacities exceeding 20,000 liters, with engineering principles ensuring and do not inhibit yields. Monoclonal antibody production via , developed in 1975 by Georges Köhler and , involves immunizing animals, fusing antigen-specific B cells with immortal myeloma cells using , and selecting clones via to yield stable, homogeneous antibody secreters screened for affinity. Modern refinements include recombinant expression in CHO cells and for humanized variants, supporting therapeutics like rituximab approved in 1997, with global production exceeding 500 metric tons annually by 2020. Additional tools include DNA microarrays, which hybridize labeled nucleic acids to immobilized probes on chips to quantify or polymorphisms, enabling high-throughput since their commercialization in the late 1990s. These techniques collectively underpin biotechnology's capacity for precise molecular manipulation, though their efficacy depends on empirical validation amid potential biases in academic reporting favoring positive outcomes.

Historical Development

During the , circa 10,000–9000 BCE in the , humans domesticated wild plants such as emmer and by selecting for traits like non-shattering seed heads and larger grains, transforming them into staple crops that supported sedentary societies. Animal domestication followed, with sheep and goats bred around 9000–8000 BCE for meat, milk, and wool, involving intentional selection for heritable traits that enhanced productivity. These practices constituted early via artificial selection, yielding domesticated varieties distinct from their wild progenitors, such as teosinte evolving into through between 6000 and 10,000 years ago in . Fermentation emerged as a key ancient biotechnological technique for and production, harnessing microorganisms without knowledge of their role. brewing evidence dates to 9000–8000 BCE in the , where produced alcoholic beverages using ambient yeasts, with Sumerian and Babylonian records confirming practices by 7000 BCE. In by 4000 BCE, yeast-mediated leavening revolutionized bread-making, while similar processes yielded wine from grapes fermented around 6000 BCE in regions like the . biotechnology included and cheese production starting circa 6000 BCE, relying on to ferment , with cheese-making traced to 7000–4000 years ago through animal processing. Pre-modern advancements built on these foundations, incorporating refined and in medieval and . By the 13th–14th centuries, European agriculture featured three-field and improved breeds through continued selection, enhancing yields and resilience. In , techniques for soy products like and , developed over millennia, utilized fungi and for protein preservation, while —selective breeding of silkworms for —dates to around 2700 BCE, involving controlled rearing and genetic propagation of . These methods, grounded in observable cause-and-effect without mechanistic insight, laid empirical groundwork for later scientific biotechnology by demonstrating biological systems' manipulability for human benefit.

Modern Foundations (19th-20th Century)

The foundations of modern biotechnology emerged in the through advances in and understanding microbial es. Louis Pasteur's experiments in the 1850s and 1860s demonstrated that specific microorganisms cause particular types of , refuting and establishing that ferments sugar into alcohol and under anaerobic conditions. In 1862, Pasteur developed , heating wine and beer to 60–70°C to kill spoilage microbes while preserving quality, a later applied to in 1882 to reduce transmission via contaminated dairy. These findings shifted from empirical craft to scientifically controlled es, enabling reliable industrial applications. A pivotal biochemical breakthrough occurred in 1897 when Eduard Buchner extracted , an from cells, and showed it could ferment sugar into alcohol without intact living cells, disproving —the notion that required a "life force." This cell-free fermentation earned Buchner the 1907 and laid the groundwork for enzymology, revealing that non-living extracts could catalyze complex reactions, which influenced subsequent isolations and industrial biocatalysis. Concurrently, provided a hereditary framework: Gregor Mendel's 1866 publication of pea plant hybridization experiments outlined the laws of segregation and independent assortment, positing discrete heritable units (later genes) that predict trait ratios like 3:1 in monohybrids, though overlooked until rediscovery in 1900. These principles enabled selective breeding advancements in and foreshadowed genetic manipulation. Industrial biotechnology scaled during World War I, exemplified by Chaim Weizmann's 1916 anaerobic fermentation process using Clostridium acetobutylicum bacteria to convert starch from corn or potatoes into acetone, yielding up to 30% of fermentable substrate as product. This met Britain's demand for acetone in cordite production—over 10,000 tons annually by 1918—after German submarine blockades cut wood-derived supplies, with factories in Britain and later the U.S. producing millions of gallons via submerged fermentation. Post-war, such microbial processes expanded to solvents like butanol. In pharmaceuticals, Alexander Fleming's 1928 observation of Penicillium rubens mold secreting a substance inhibiting Staphylococcus growth marked antibiotic discovery; he isolated penicillin and published findings in 1929, though purification scaled only in the 1940s. By 1919, aerobic fungal fermentation produced citric acid via Aspergillus niger, initiating large-scale organic acid manufacturing. These developments integrated microbiology, enzymology, and genetics into applied biotechnology, transitioning from artisanal to engineered bioprocesses.

Recombinant DNA Era (1970s-1990s)

The development of recombinant DNA technology in the early 1970s revolutionized biotechnology by enabling the deliberate combination and propagation of genetic material from disparate sources. In 1972, researchers David Jackson, Robert Symons, and Paul Berg created the first chimeric DNA molecule by ligating SV40 viral DNA to lambda phage DNA, demonstrating the feasibility of joining DNA fragments in vitro. Building on this, in November 1972, Stanley Cohen of Stanford University and Herbert Boyer of the University of California, San Francisco, collaborated to insert antibiotic resistance genes from one bacterial plasmid into another using EcoRI restriction enzyme and DNA ligase, producing stable recombinant plasmids that replicated in Escherichia coli host cells. Their 1973 experiments marked the first successful cloning of recombinant DNA in a living organism, laying the groundwork for gene manipulation across species. Concerns over risks, including unintended gene transfer or creation, led to proactive self-regulation by . In July 1974, key figures including Berg, , and Boyer called for a voluntary moratorium on certain recombinant experiments until risks could be assessed. This culminated in the February 1975 Molecules, attended by over 140 , where participants classified experiments by risk levels and recommended physical and biological containment measures, such as using disabled host-vector systems. The conference's recommendations directly informed the U.S. National Institutes of Health's 1976 Recombinant DNA Research Guidelines, which standardized protocols and permitted low-risk experiments to resume, balancing innovation with precaution. Commercialization accelerated in the late 1970s, transforming from a research tool into an industrial platform. Boyer co-founded in 1976 with venture capitalist Robert Swanson to exploit the technology for . In August 1978, researchers, led by Kleid, achieved the first synthesis of insulin via recombinant methods, expressing synthetic A and B chain separately in E. coli and combining them chemically. This effort, in collaboration with , yielded Humulin, approved by the FDA in October 1982 as the first recombinant therapeutic protein, reducing reliance on animal-derived insulin and enabling scalable production. The Cohen-Boyer technique, patented in 1980 after a 1974 application, was licensed non-exclusively by Stanford and UCSF, generating over $255 million in royalties by 1997 and fueling dozens of biotech startups. The 1980s and 1990s saw expanded applications, including recombinant human growth hormone (somatropin, approved 1985 for treating deficiency disorders), interferon alfa-2b (Intron A, approved 1986 for cancers and hepatitis), hepatitis B vaccine (Recombivax HB, approved 1986), and tissue plasminogen activator (Activase, approved 1987 for thrombolysis). These products demonstrated recombinant DNA's capacity for producing complex eukaryotic proteins in prokaryotic systems, though challenges like glycosylation required later shifts to mammalian cell expression. By the 1990s, the technology underpinned gene therapy trials, with the first approved human trial in 1990 for severe combined immunodeficiency using retroviral vectors to insert corrective genes. Overall, the era established biotechnology as a distinct industry, with global market growth from nascent ventures to over 1,300 companies by 1999, driven by therapeutic outputs exceeding $10 billion annually.

Gene editing technologies advanced significantly with the adaptation of CRISPR-Cas9 in 2012, allowing precise, targeted modifications to DNA sequences in prokaryotic and eukaryotic cells. Originally observed as bacterial adaptive immunity mechanisms in the 1980s and 1990s, CRISPR-Cas9 was repurposed for genome engineering through key experiments demonstrating its use as a programmable nuclease, outperforming prior methods like zinc-finger nucleases in efficiency and accessibility. This tool has enabled applications in functional genomics, such as knocking out specific genes to study loss-of-function effects, though off-target edits remain a challenge requiring ongoing refinements like high-fidelity variants. Synthetic biology expanded genomic capabilities by engineering novel biological systems, with milestones including the 2000 construction of synthetic genetic circuits like toggle switches in E. coli and the 2010 creation of the first synthetic bacterial cell by Craig Venter's team, which transplanted a chemically synthesized into a recipient cell. These developments integrated with de novo design principles, enabling applications in production and , where genomes are rewired to optimize pathways for industrial outputs. Messenger RNA (mRNA) technologies, building on genomic insights into protein coding, gained prominence in the for therapeutic delivery, culminating in the rapid deployment of mRNA-based vaccines in 2020 by and /, which encoded the to elicit immune responses without genomic integration. This approach leverages synthetic mRNA stabilized by modifications like analogs, offering faster development than traditional vaccines and extending to and infectious diseases.

Risks, Criticisms, and Controversies

Biotechnology faces various risks and criticisms, including unintended ecological effects such as gene flow to wild species and biodiversity loss, health concerns like potential allergens or off-target genetic edits, ethical issues including inequality in access and the prospect of "designer babies," and biosecurity threats from potential misuse for bioweapons. These debated concerns are supported by empirical discussions and regulatory responses in the subsections below.

Biosafety and Health Risks

Biosafety in biotechnology encompasses protocols to prevent unintended exposure to or release of biological agents, classified into Biosafety Levels (BSL) 1 through 4 based on agent risk and requirements. Laboratory-acquired infections and breaches have occurred historically, with contributing to 67-79% of potential exposures in BSL-3 facilities as of 2019 analyses. Between 1975 and 2016, at least 71 documented incidents involved accidental or intentional high-risk pathogen exposures, including infections from agents like and . Notable examples include the 1977 re-emergence of H1N1 , which caused an estimated 700,000 deaths worldwide and was traced to a escape during research, and the 1979 Sverdlovsk anthrax outbreak in the , linked to a bioweapons facility failure resulting in at least 66 deaths. These events underscore causal vulnerabilities in systems, though rigorous BSL protocols and dual-use research oversight have reduced incidence rates over time, with global mappings from 2000-2021 identifying fewer than 300 reported breaches despite expanded biotech activity. Health risks from biotechnological products primarily involve potential toxicity, allergenicity, or unintended genetic effects, though empirical data from long-term studies indicate low realized hazards. Genetically modified organisms (GMOs) in and , cultivated commercially since 1996, show no of unique health dangers in peer-reviewed meta-analyses; for instance, a 2014 review of 147 studies found GM adoption reduced use by 37%, boosted yields by 22%, and yielded no substantiated links to cancer, , or organ damage after over 1.78 billion years of collective animal feeding exposure. Twenty-eight years of GMO deployment as of 2024 have produced no verified consumer harm, with regulatory assessments confirming compositional equivalence to non-GM counterparts and negligible transfer risks under current testing. Criticisms alleging or resistance transfer from GM plants persist in some literature, but these lack causal validation in controlled trials and often stem from methodological flaws in studies dismissed by consensus reviews. In advanced applications like CRISPR-Cas9 gene editing, off-target effects—where the cleaves unintended genomic sites—pose theoretical risks of mutations leading to oncogenesis or heritable changes, with early studies detecting rates exceeding 50% in some cellular models. However, refined guide RNAs, high-fidelity variants, and predictive algorithms have reduced off-target activity to near-undetectable levels in recent iterations, and ongoing clinical trials for conditions like report no adverse events attributable to such effects as of 2023, though long-term surveillance remains essential due to incomplete understanding of epigenetic repercussions. Biotechnological platforms, such as mRNA and viral vectors, carry rare acute risks including thrombosis with thrombocytopenia (TTS) observed in approximately 1-2 per million doses of certain adenovirus-based vaccines, causally linked via antibodies, and myocarditis at rates of 1-10 per 100,000 in young males post-mRNA dosing. These events, while prompting enhanced screening, represent fractional risks against baseline infection hazards, with no evidence of broader genomic integration or fertility impacts from large-scale data. Antibiotic resistance, exacerbated by clinical overuse rather than direct biotech engineering, sees biotechnological interventions like and countermeasures showing promise in preclinical models without amplifying resistance dissemination. Overall, while theoretical pathways to harm exist, causal evidence prioritizes mitigated risks over systemic threats, tempered by source biases in alarmist reporting from non-peer-reviewed outlets.

Environmental Concerns

One primary environmental concern with genetically modified (GM) crops involves , where transgenes transfer to wild relatives or non-GM crops via cross-pollination or , potentially leading to reduced in wild populations. Documented cases include gene flow from GM canola to wild mustard in and from GM rice to weedy rice in , raising risks of creating hybrid weeds with enhanced fitness. However, comprehensive reviews indicate that while gene flow occurs, its long-term ecological impacts on are often limited and context-dependent, with no widespread evidence of irreversible harm to ecosystems as of 2017 assessments. The widespread adoption of herbicide-tolerant GM crops, such as those engineered for resistance, has contributed to the of herbicide-resistant "superweeds," necessitating increased herbicide use and , which can degrade and . By 2023, over 250 species globally exhibited resistance to multiple herbicides, partly linked to GM crop management practices in the . Empirical data from long-term field studies show mixed outcomes: while some regions report heightened weed pressure, others demonstrate net reductions in overall applications due to precise targeting enabled by GM traits. In biofuel production, biotechnology-driven expansion of dedicated crops like and biodiesel has induced indirect changes, including and conversion of grasslands, elevating beyond baselines in certain scenarios. Life-cycle analyses estimate that indirect change (ILUC) from U.S. added 20-50 grams of CO2-equivalent per megajoule in early models, though updated economic modeling suggests minimal direct links to tropical for North American policies. Synthetic biology applications, including engineered microbes for or industrial processes, pose risks from accidental escape into natural environments, where they could outcompete native species or facilitate , altering microbial communities. Laboratory incidents and modeling predict potential propagation with unforeseen cascading effects on or aquatic ecosystems, prompting calls for stringent . Peer-reviewed assessments highlight that while containment technologies exist, complete prevention of release remains challenging, particularly for scalable applications. Emerging tools like gene drives, which bias inheritance to spread modifications rapidly through populations, amplify environmental risks due to their self-propagating nature, potentially causing unintended suppression of non-target species or ecosystem imbalances. National Academies reports from 2016 emphasize challenges in predicting dynamics and reversibility, with field trials for underscoring needs for spatiotemporal containment to mitigate . Risk assessments recommend ecological modeling and monitoring, as irreversible spread could disrupt food webs, though species-specific designs aim to limit off-target effects.

Ethical and Social Debates

Ethical debates in biotechnology center on the moral implications of manipulating living organisms, including concerns over dignity, the of , and the potential for exacerbating social inequalities. Critics argue that technologies like gene editing risk "playing " by altering fundamental aspects of , while proponents emphasize therapeutic benefits grounded in empirical evidence of disease alleviation, such as CRISPR-based treatments for sickle cell anemia approved by the FDA in December 2023. These debates often invoke first-principles questions about the intrinsic value of natural biological processes versus engineered improvements, with opposition rooted in fears of unintended societal shifts toward or . A focal point is germline gene editing, which introduces heritable changes to the . The 2018 announcement by Chinese scientist of editing embryos to confer resistance sparked global condemnation for bypassing ethical safeguards, leading to his imprisonment and calls for international moratoriums; in May 2025, scientific societies advocated a 10-year ban on such applications due to risks of off-target mutations and mosaicism, which could cause unforeseen health issues in edited individuals and descendants. Proponents counter that somatic editing—non-heritable modifications—has demonstrated safety in clinical trials, treating conditions like with minimal adverse events reported in 2020 trials, suggesting germline bans may unduly hinder progress against genetic diseases. Yet, ethical analyses highlight justice concerns, as enhancements could widen class divides, with wealthier groups accessing "designer" traits unavailable to others. Stem cell research exemplifies tensions between potential cures and the moral status of embryos. Embryonic stem cells, derived from blastocysts, offer pluripotency for regenerative therapies but require destroying early-stage embryos, prompting objections that this equates to ending potential human life; , while less versatile, avoid such destruction and have yielded treatments like hematopoietic stem cell transplants for since the 1960s. U.S. policy under President in 2001 restricted federal funding to existing lines, reflecting religious and ethical views equating embryos to persons, though subsequent administrations , with induced pluripotent stem cells (iPSCs) emerging in 2006 as an ethical alternative by reprogramming adult cells without embryo use. Social debates surrounding genetically modified organisms (GMOs) in focus less on verified health risks—meta-analyses of over 1,700 studies since 1996 affirm their equivalence to conventional crops in safety—and more on corporate control, labeling, and perceived unnaturalness. Public skepticism persists, with surveys showing 37% of Americans viewing GM foods as worse for health in 2020, often tied to distrust in institutions like , whose seed patents have led to farmer dependency via terminator technology fears, though empirical data indicates yield increases of 22% for insect-resistant without ecological harm. In the Global South, GM adoption lags due to regulatory hurdles and activism, yet in boosted farmer incomes by 50% from 2002-2010 per peer-reviewed studies, underscoring debates over equitable benefit distribution amid patent monopolies. Intellectual property in biotechnology raises questions of patenting life forms, with the U.S. Supreme Court's 1980 decision allowing patents on genetically engineered bacteria, extended to animals like the Harvard Oncomouse in 1988, but excluding humans to preserve dignity. Critics contend this commodifies , potentially stifling in developing nations by enforcing royalties—biotech patents cost $1-2 billion to develop, limiting access—and eroding through proprietary strains. Ethically, European directives bar patents violating "ordre public" if they exploit animals suffering or undermine genetic resource , balancing incentives with moral limits on owning higher life forms. Access inequities amplify social divides, as high-cost therapies like CAR-T cell treatments exceeding $400,000 per patient remain unaffordable in the Global South, where less than 1% of biotech benefits accrue despite 80% of global population, fostering a "biotech divide" that entrenches health disparities. Dual-use risks, such as via engineered pathogens, prompt calls for oversight, with the highlighting vulnerabilities, though empirical threat assessments indicate low probability compared to natural pandemics. These issues underscore causal realities: biotechnology's causal chains from lab to demand rigorous, evidence-based to mitigate harms while harnessing verified gains.

Regulation and Governance

International Agreements

The Convention on Biological Diversity (CBD), adopted on 5 June 1992 and entered into force on 29 December 1993, serves as a foundational international framework addressing biotechnology in the context of conserving biological diversity, promoting sustainable use of its components, and ensuring fair benefit-sharing from genetic resources. Article 8(g) requires parties to regulate risks from living modified organisms (LMOs) resulting from biotechnology that may harm biodiversity, while Article 19 mandates cooperation in handling biotechnology applications, including safe procedures for LMO transfers and notifications for field releases. The treaty defines biotechnology broadly as any technological application using biological systems or derivatives to produce or modify products, encompassing processes from traditional breeding to genetic engineering. As of 2025, the CBD has 196 parties, though implementation varies, with some nations critiquing its emphasis on precautionary approaches that may hinder innovation without robust risk-based evidence. The Cartagena Protocol on Biosafety, a supplementary agreement to the CBD, was adopted on 29 January 2000 in Montreal and entered into force on 11 September 2003, focusing specifically on the safe handling, transport, and use of LMOs generated through modern biotechnology, such as genetically modified crops and microbes. It establishes an advance informed agreement procedure for transboundary movements of LMOs intended for intentional release into the environment, requiring exporters to provide risk assessments demonstrating no significant adverse effects on biodiversity or human health. With 173 parties as of 2023, the protocol prioritizes the precautionary principle, allowing import bans based on potential risks even absent conclusive scientific proof of harm, which has led to debates over its impact on global agricultural trade and food security. The Nagoya-Kuala Lumpur Supplementary Protocol, adopted in 2010 and effective from 2018, complements it by addressing liability and redress for damage from LMOs, defining damage as adverse changes to conservation and sustainable use of biodiversity. The (BWC), opened for signature on 10 April 1972 and entered into force on 26 March 1975, prohibits the development, production, acquisition, stockpiling, or retention of microbial or other biological agents or toxins for hostile purposes, directly implicating biotechnology's dual-use potential. Article I bans such agents in quantities or types exceeding peaceful purposes, without defining specific biotechnological thresholds, relying instead on national implementation to distinguish legitimate research from weaponization risks like engineered pathogens. Ratified by 185 states parties as of 2025, the BWC lacks formal verification mechanisms, prompting ongoing review conferences to address advances in and gene editing that could enable covert bioweapon programs. Critics note its effectiveness hinges on self-reporting, with historical non-compliance allegations underscoring enforcement challenges in an era of rapid biotech proliferation. Other multilateral efforts, such as the Organisation for Economic Co-operation and Development ()'s 1986 Recommendation on Safety Considerations, provide non-binding guidelines for harmonizing assessments across member states, influencing national regulations on contained and field uses of genetically modified organisms. Similarly, World Health Organization (WHO) norms, including the 2021 framework on editing, offer advisory standards for ethical oversight of heritable modifications but lack status, emphasizing risk evaluation over prohibition. These instruments collectively aim to balance biotech innovation with risk mitigation, though gaps persist in covering emerging fields like , where international consensus remains aspirational rather than codified.

National Policies and Examples

In the , biotechnology products are regulated under a coordinated framework established in 1986 and updated through , with oversight divided among the (FDA), the (USDA), and the Environmental Protection Agency (EPA). The FDA evaluates food and drug from genetically engineered plants and animals, the USDA assesses to agriculture from plant pests or diseases, and the EPA regulates pesticidal substances produced by biotech crops; this product-based approach focuses on and rather than the modification process itself. In May 2024, the agencies issued a joint regulatory plan to streamline approvals for categories like microbial products and gene-edited plants, aiming to reduce redundancies while maintaining standards. The European Union employs a precautionary, process-based regulatory regime for genetically modified organisms (GMOs), requiring pre-market authorization under Directive 2001/18/EC for environmental releases and Regulation (EC) No 1829/2003 for food and feed uses, with mandatory labeling for products containing more than 0.9% approved GM material. This framework emphasizes potential long-term risks, leading to fewer GMO approvals compared to other regions; however, in February 2024, the European Parliament voted to exempt certain gene-edited crops from stringent GMO rules if no foreign DNA is introduced, reflecting pressures to align with global competitiveness. National variations exist, such as Germany's opt-out provisions under EU rules, but overall implementation prioritizes traceability and public consultation. China has pursued an aggressive biotechnology policy to bolster and innovation, issuing guidelines in 2022 for safety assessments of gene-edited crops that treat them similarly to conventional breeding if no transgenes are present, under the Ministry of Agriculture and Rural Affairs. The 2021 Biosecurity Law strengthened oversight of high-risk biotech activities, including human germline editing, following ethical controversies like the 2018 CRISPR baby scandal, which prompted civil penalties and ethical guidelines in 2020. In February 2025, new guidelines promoted gene-editing tools for crops like and soybeans, with over 20 gene-edited varieties approved for trials by 2023, positioning as a leader in applied biotech despite concerns over transparency in state-driven research. In India, biotechnology regulation falls under the 1989 Rules for the Manufacture, Use, Import, Export, and Storage of Hazardous Microorganisms, Genetically Engineered Organisms, and Cells, administered by the Genetic Engineering Appraisal Committee (GEAC) within the Ministry of Environment, Forest and Climate Change, focusing on environmental and health biosafety for GM crops. Bt cotton, approved in 2002, remains the only commercialized GM crop, with approvals for GM mustard stalled by litigation over long-term ecological impacts; in June 2025, the Supreme Court urged formulation of a comprehensive national policy to balance science-based approvals with risk assessment. This cautious stance reflects public and activist opposition, contrasting with faster adoption in neighboring countries. Brazil exemplifies a Latin American approach with its 1995 Biosafety Law and 2005 GMO-specific , creating the National Biosafety Technical Commission (CTNBio) to evaluate and approve biotech products, resulting in widespread GM soybean and corn cultivation covering over 50 million hectares by 2023. Policies emphasize economic benefits for while requiring containment measures for hotspots, though enforcement challenges persist in illegal plantings.
