Nostoc

Common species include Nostoc commune, Nostoc azollae, Nostoc punctiforme, Nostoc flagelliforme, and Nostoc pruniforme.

Nostoc can be found in freshwater environments, on tree trunks, rocks, and as symbionts in lichens and certain bryophytes.

Nostoc are important for nitrogen fixation, enriching soil nutrients. They also have potential uses in biofuel production, bioremediation, and the pharmaceutical industry due to their antibacterial and antiviral properties.

Nostoc reproduces vegetatively through fragmentation and asexually by forming akinetes. They also reproduce using heterocysts.

Nostoc is a genus of blue-green algae or cyanobacteria, found mainly in freshwater environments. They are capable of photosynthesis and nitrogen fixation.
