Azotobacter is the free-living bacteria that increases the yield of paddy in the soil. It fixes atmospheric nitrogen into forms that are accessible to plants, thereby enhancing soil fertility and supporting crop growth.
Tuberculosis is caused by bacteria. Specifically, the bacterium Mycobacterium tuberculosis is responsible for the disease, which primarily affects the lungs but can also impact other parts of the body.
Leghemoglobin functions in nitrogen fixation by absorbing oxygen. It creates a low-oxygen environment in the root nodules, which is necessary for the nitrogen-fixing enzyme nitrogenase to function effectively and fix atmospheric nitrogen.
Beans are helpful in nitrogen fixation. They form symbiotic relationships with nitrogen-fixing bacteria in their root nodules, converting atmospheric nitrogen into a form usable by the plant and enriching the soil.
