One of the free-living anaerobic nitrogen fixer is:
Open in App
Solution
The correct option is C Clostridium
Nitrogen fixers can be of two types - free-living and symbiotic. Free-living or non-symbiotic nitrogen fixers are the microorganisms that live freely or outside the plant cell. For example free-living non-photosynthetic aerobic nitrogen fixing bacteria are Azotobacter, Beijerinckia and Derxia. Free-living non-photosynthetic anaerobic nitrogen fixing bacteria include Clostridium. Symbiotic nitrogen fixers are microbes which are mutually associated with plants and fix atmospheric nitrogen within plant cell. Example of a nitrogen fixer is Rhizobium that fixes nitrogen in roots of leguminous plants.
