Introduction Rhizobium is a remarkable bacterium known for its unique symbiotic relationship with the roots of leguminous plants. Found primarily in root nodules of plants like peas, beans, and lentils, Rhizobium plays a crucial role in biological nitrogen fixation. This process converts atmospheric nitrogen, which plants cannot directly use, into ammonia—a soluble form that plants […]
Introduction Bacillus subtilis is a Gram-positive, endospore-forming bacterium commonly found in soil, air, water, and decaying plant matter. This rod-shaped, motile microorganism is a facultative aerobe, meaning it can survive in both oxygen-rich and oxygen-poor environments. Known for producing resistant endospores, B. subtilis can endure extreme heat, dehydration, and UV radiation. Thanks to its well-studied
