What is a common name for nitrogen-fixing bacteria?

Answer 1

Diazotroph is the common name for nitrogen-fixing bacteria and micro-organisms.

Specifically, the term designates organisms that are capable of turning atmospheric nitrogen into more usable forms, such as ammonia. It includes such soil-dwellers as Frankia genus members living symbiotically with actinorhizal (beech, cucurbit and rose-related orders) plants and Rhizobia genus members living symbiotically with leguminous (bean-related order) plants. Cyanobacteria living symbiotically with lichens and liverworts also number among the diazotrophs of greater name recognition.

Answer 2

There is not scientific name for nitrogen fixing bacteria. This group includes cyanobacteria (blue green algae), symbiotic bacteria like Rhizobium and also free living bacteria like Azotobacter.

Answer 3

Rhizobia is a common name for nitrogen-fixing bacteria that form symbiotic relationships with certain plants, like legumes, in which they help convert atmospheric nitrogen into a form that plants can utilize for growth.
