Nodularia is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae.^[1] They occur mainly in brackish or salinic waters, such as the hypersaline Makgadikgadi Pans,^[2] 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.

Morphology

Nodularia is forms solitary filaments or groups of filaments. They reproduce by the formation of hormogonia, filament breakage, and by akinetes .^[3]
