Question

name the microorganisms which can fix atmos pheric nitrogen in soil?​

Answer 1

Answer:

rhizobium

Explanation:

Rhizobia are a "group of soil bacteria that infect the roots of legumes to form root nodules".[2] Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen.

Answer 2

Answer: Two kinds of nitrogen-fixing bacteria are recognized. The first kind, the free-living (nonsymbiotic) bacteria, includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium.
