👉 Rhizobium is a type of bacteria that lives in symbiotic relationships with plant cells, often forming a biofilm on the surface of the plant roots. This symbiosis helps plants resist pathogens and pests by absorbing nutrients from the soil and releasing them as a defense mechanism. Rhizobacteria are important components of the microbiome, which is a complex network of microorganisms that inhabit our digestive system and play key roles in nutrient absorption, digestion, and metabolism.
