1. Free-living (non-symbiotic) bacteria: cyanobacteria (or blue-green algae), Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium. 2. Mutualistic (symbiotic) bacteria: Rhizobium, associated with leguminous plants; Frankia, associated with certain dicotyledonous species; and certain Azospirillum species, associated ...
Only certain prokaryotic organisms (some bacteria and cyanobacteria) are capable of fixing N 2. Such microbes are called N 2-fixers. These N 2-fixing microbes contain an exclusive enzyme, Nitrogenase that is capable of reducing nitrogen. Azotobacter is the free-living N 2-fixing bacteria. It is aerobic i.e., it requires oxygen for respiration.

Nitrogen-fixing bacteria are those bacteria which fixes atmospheric nitrogen and make it available for the plants. There are 2 types of nitrogen-fixing bacteria, free-living (nonsymbiotic) bacteria and non free living (symbiotic) bacteria. Examples of free-living bacteria includes , cyanobacteria like Anabaena and Nostoc, Azotobacter, Clostridium.
A free living aerobic and non-photosynthetic nitrogen fixing bacterium is. View Solution.
There are some nitrogen fixing bacteria which converts atmospheric nitrogen into ammonia which is readily available to plants. Anabaena is a free-living as well as symbiotic nitrogen fixing bacteria. Clostridium is a free-living, anaerobic nitrogen fixing bacteria. Azotobacter are free-living, aerobic, and non-photosynthetic nitrogen fixing ...
Azotobacter is a free-living nitrogen-fixing bacteria. Rhizobium lives in symbiotic association with roots of leguminous plants. Hence, the correct answer is ' Azotobacter '
Two kinds of nitrogen-fixing bacteria are recognized. 1. Free-living (non-symbiotic) bacteria: cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium. 2.
Verified by Toppr. Nitrogen-fixing bacteria are those bacteria which fixes atmospheric nitrogen and make it available for the plants. There are 2 types of nitrogen-fixing bacteria, free-living (nonsymbiotic) bacteria and non free living (symbiotic) bacteria.

This inert nitrogen is fixed into biologically active ammonia by free living or symbiotic bacteria and other microorganisms. The free living bacteria are present in soil where they perform nitrogen fixation; example: Azotobacter, Azospirillum and Clostridium. This makes option B correct. The finger like projections on roots of legumes, termed ...
