Question

Which bacteria are Nitrogen Fixing?

Answer 1

Nitrogen-fixing bacteria:

1. Nitrogen-fixing microbes are microorganisms fit for changing air nitrogen into fixed nitrogen (inorganic mixtures usable by plants).
2. In excess of $90\%$ of all nitrogen, obsession is affected by these organic entities, which accordingly assume a significant part in the nitrogen cycle.

Types:

1. The principal kind, the free-living (nonsymbiotic) microbes, incorporates the cyanobacteria (or blue green growth) Anabaena and Nostoc and genera like Azotobacter, Beijerinckia, and Clostridium.
2. The subsequent kind involves the mutualistic (harmonious) microorganisms; models incorporate Rhizobium, related with leguminous plants (e.g., different individuals from the pea family); Frankia, related to specific dicotyledonous species and certain Azospirillum species, related with cereal grasses.
3. A few instances of nitrogen-fixing microbes are Azotobacter, Beijerinckia, Rhodospirillum, Rhizobium, Frankia, cyanobacteria like Anabaena, Nostoc, and so forth.
