Question

Give two examples of nitrogen-fixing aerobic microbes that are free-living.

Answer 1

Nitrogen-fixing microbes:

1. There are two types of nitrogen-fixing bacteria.
2. Cyanobacteria Anabaena and Nostoc, as well as genera like Azotobacter, Beijerinckia, and Clostridium, are among the free-living bacteria.
3. As a result, Beijerinckia and Azotobacter are examples of nitrogen-fixing aerobic microbes that are free-living.
