Rhizobium.
The bacteria live in the plant cells, located on the root, and form nodules. These nodules convert nitrogen gas in the soil to usable energy for the plant. In return, the bacteria have a safe place to live and reproduce.
these bacteria are known as rhizobium. they synthesis the atmospheric nitrogen into nitrates & nitrites soluble in soil
Ground nuts are legumes. Groundnut being a legume crop utilizes the nitrogen in the atmosphere by nitrogen fixation in association with a group of bacteria belonging to Rhizobium family. The Rhizobium bacteria penetrate the roots of legumes and form root nodules .
Special class of bacteria called Rhizomes live on the roots of leguminus plants. They take free nitrate and nitrites from the environment and change to a form that can be readily used by plants. Relationship between nitrogen fixing bacteria and plants is called Symbiosis.
Rhizobium bacteria obtain moisture from the surrounding soil or plant roots through a process called osmosis. They can absorb water directly through their cell membrane to support their metabolic functions and nitrogen-fixing activities in symbiosis with legume plants.
Rhizobia bacteria are commonly associated with leguminous plants. These bacteria have a symbiotic relationship with legumes, helping them fix nitrogen from the air into a form that the plants can use for growth.
Legumes such as clover, beans, and soybeans have symbiotic relationships with nitrogen-fixing bacteria like Rhizobium, allowing them to convert atmospheric nitrogen into a form that plants can use. These bacteria live in nodules on the plant's roots and help enrich the soil with available nitrogen.
The two main groups of bacteria responsible for nitrogen fixation are Rhizobium found in legume root nodules, and Azotobacter found in the rhizosphere of various plants. Rhizobium forms a mutualistic relationship with legumes, providing fixed nitrogen in exchange for sugars, while Azotobacter functions as a free-living nitrogen fixer in the soil.
