All Filamentous Cyanobacteria

Filamentous Cyanobacteria is a Browse By group of the Nature Atlas that gathers cyanobacteria that grow as long threads of cells, free floating or in mats, in fresh, brackish and alkaline waters, and that fit none of the marine, nostoc family or toxin-producing planktonic groups of this subcategory, such as Spirulina, the helical filaments of Arthrospira that are cultivated and dried as a food supplement. An entry belongs here when its own cited article describes a filamentous cyanobacterium, or a product made from one. It excludes the groups already named in this subcategory. The group lets a reader compare a farmed food filament with the bloom-forming and ocean-going cyanobacteria beside it.
