Nodularia
Nodularia is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae. They occur mainly in brackish or salinic waters, such as the hypersaline Makgadikgadi Pans, the Peel-Harvey Estuary in Western Australia or the Baltic Sea. Nodularia cells occasionally form heavy algal blooms. Some strains produce a cyanotoxin called nodularin R, which is harmful to humans.
The type species for the genus is Nodularia spumigena Mertens ex Bornet & Flahault, 1886.
Nodularia may form solitary filaments or groups of filaments. They reproduce by the formation of hormogonia, filament breakage, and by akinetes .
As climate change influenced the local sea surface temperature, N. spumigena in the Baltic Sea changed their photosynthetic optimum temperature too. This was revealed by a sediment core from the Eastern Gotland Basin corresponding to 1987–2020, providing strains of N. spumigena that were revived and tested in the lab.
