Rhizobium leguminosarum bv. trifolii WSM1325

Rhizobium leguminosarum bv. trifolii WSM1325 is a Gram-negative, rod-shaped bacterium primarily found in soil. This organism is classified as a chemoheterotroph, utilizing organic compounds for energy, and is obligately aerobic, requiring oxygen for growth. R. leguminosarum bv. trifolii WSM1325 is characterized by its single-cell arrangement and possesses flagella, which contributes to its mobility. This bacterium is mesophilic, thriving within a moderate temperature range, and is known for its nonsporulating nature. It features a unique cellular structure comprising two membranes and has a complex genetic makeup with a total of six replicons. Importantly, R. leguminosarum bv. trifolii WSM1325 engages in a symbiotic relationship with leguminous plants, specifically forming root nodules where nitrogen fixation occurs, thereby enriching the soil with bioavailable nitrogen. Notably, this strain is non-pathogenic, indicating its role as a beneficial organism rather than a disease-causing agent. The symbiotic interactions facilitated by R. leguminosarum bv. trifolii WSM1325 can enhance soil fertility and contribute to sustainable agricultural practices by reducing the need for chemical fertilizers. The presence of this bacterium in the soil underscores its ecological importance, highlighting its potential in promoting plant growth and maintaining soil health through natural nitrogen fixation processes.
