Similarly one may ask, which bacteria is responsible for nitrogen fixation?
Examples of symbiotic nitrogen-fixingbacteria include Rhizobium, which is associated with plants inthe pea family, and various Azospirillum species, which areassociated with cereal grasses.
Also, what does the plant do for the nitrogen fixing bacteria? Nitrogen-fixing bacteria aremicroorganisms present in the soil or in plant roots thatchange nitrogen gases from the atmosphere into solidnitrogen compounds that plants can use in thesoil.
Keeping this in view, is Rhizobium a nitrogen fixing bacteria?
Rhizobia are diazotrophic bacteria thatfix nitrogen after becoming established inside the rootnodules of legumes (Fabaceae). To express genes for nitrogenfixation, rhizobia require a plant host; they cannotindependently fix nitrogen. In general, they are gramnegative, motile, non-sporulating rods.
Are nitrogen fixing bacteria aerobic or anaerobic?
For this reason, many bacteria cease productionof the enzyme in the presence of oxygen. Manynitrogen-fixing organisms exist only inanaerobic conditions, respiring to draw down oxygen levels,or binding the oxygen with a protein such asleghemoglobin.
