Rhizobium leguminosarum

Rhizobium leguminosarum is a bacterium which lives in a mutualistic symbiotic relationship with legumes, and has the ability to fix free nitrogen from the air.[1] R. leguminosarum has been very thoroughly studied--it has been the subject of more than a thousand publications.[1]

Morphology[edit]

Rhizobium leguminosarum is a Gram-negative, motile, rod-shaped, aerobic bacterium.[2]

Common biovars[edit]

R. leguminosarum biovar trifolii, and R. leguminosarum biovar viciae are the most commonly studied biovars of R. leguminosarum, with certain studies seemingly treating R. trifolii as its own species.[3]

Uses[edit]

Research has been carried out into the role that R. leguminosarum could play in promoting growth of canola and lettuce.[4]
