Question

Which bacteria fixes nitrogen in the soil?

Answer 1

Rhizobium:

1. Several Rhizobium strains may fix nitrogen in root nodules, and a few Rhizobium bacteria species include Rhizobium leguminosarum and Rhizobium alamii.
2. Beans are an example of a leguminous plant.
3. Nitrogen fixing bacteria are microbes or bacteria that fix nitrogen in soil.
4. Many bacteria species may fix nitrogen in soil, but the most common are Azotobacter, Rhizobia, Acetobacter, and some blue green algae.
5. These bacteria can fix atmospheric nitrogen and transform it into useable nitrogenous compounds that plants may use for photosynthesis as well as the creation of plant proteins and other chemicals.
6. Nitrogen fixation is the process of converting atmospheric nitrogen to a useful nitrogen form such as ammonia or nitrogen oxide. Nitrogen fixing bacteria can be free-living or symbiotic.
7. Free-living soil bacteria, such as azotobacter, can develop partnerships with plants and aid in nitrogen fixation by converting atmospheric nitrogen to ammonia.
8. Rhizobia are nitrogen-fixing bacteria that exist in symbiotic relationships with the root nodules of leguminous plants.
9. Symbiotic bacteria require a plant host since they cannot fix nitrogen; rhizobia are important nitrogen suppliers.
10. Plants may easily employ the transformed nitrogen in soil for plant protein synthesis and other chemical creation.
