How do you grow Nostoc?
Soil Nostoc can be easily isolated on BG11o agar, supplemented with cyclohexamide (to avoid algae and fungi). Use diltion series at least to10–4 -10–6 As Nostoc a nitrogen-fixer itself, BG11o will be the best way to get rid off non-fixers (like oscilatorians).
Can Anabaena fix nitrogen?
Anabaena is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern.
How does Nostoc reproduce?
Nostoc reproduce vegetatively or asexually by spore formation. The vegetative reproduction is by fragmentation. Small colonies can grow attached to a large colony and later form separated colonies. Hormogonia are short and free filaments.
