In return, the bacteria provides the plant with nitrogen in forms that the plant can take in. Nitrogen fixing bacteria change nitrogen from the air into nitrogen compounds such as ammonia, nitrate, and nitrogen dioxide. They do so, through two living arrangements. One's as free living bacteria in the soil. The other's in association with plants of the Fabaceae and Leguminosae families, such as beans and peas.
Rhizobia are soil bacteria that fix nitrogen (diazotrophs) after becoming established inside root nodules of legumes (Fabaceae). In order to express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen.pecific strains of rhizobia are required to make functional nodules on the roots able to fix the N2. Having this specific rhizobia present is beneficial to the legume, as the N2 fixation can increase crop yield.
