Rhizobium leguminosarum is a Gram-negative, motile, rod-shaped bacterium that lives in a mutualistic symbiotic relationship with legumes and can fix free nitrogen from the atmosphere. Rhizobium leguminosarum is found in soil, particularly in association with the root nodules of leguminous plants such as peas, beans, and clover
Rhizobium leguminosarum plays a vital role in the nitrogen cycle by converting atmospheric nitrogen (N₂) into ammonia (NH₃) through biological nitrogen fixation. This process provides an essential nutrient source for leguminous plants, enhancing their growth in nitrogen-deficient soils and reducing the need for synthetic fertilizers. B
The presence of R. leguminosarum in agricultural systems helps mitigate environmental pollution by decreasing the excessive use of nitrogen-based fertilizers, which can lead to waterway contamination and greenhouse gas emissions. As a key player in soil microbiomes, this bacterium fosters interactions with other beneficial microorganisms, further enhancing plant health and productivity.
