Sinorhizobium meliloti SM11

Sinorhizobium meliloti SM11 is a Gram-negative, aerobic bacterium characterized by its rod shape and motility, facilitated by the presence of flagella. This species thrives in multiple habitats, demonstrating its adaptability in various environmental conditions. S. meliloti SM11 exhibits mesophilic characteristics, with an optimal growth temperature of 25°C, although it can survive within a broader temperature range typical of mesophiles. The genetic structure of S. meliloti SM11 includes two replicons, which are essential for its reproductive and metabolic processes. This feature contributes to its successful adaptation and functionality in diverse ecosystems. The organism is significant in agricultural settings, particularly due to its role in symbiotic nitrogen fixation with leguminous plants, which can enhance soil fertility and contribute to sustainable agricultural practices. Understanding the traits of Sinorhizobium meliloti SM11 can provide insights into its ecological role, particularly in nitrogen cycling and plant health. Its ability to thrive in various habitats and its mesophilic nature suggest that it can play a critical role in various ecosystems, potentially improving soil quality and promoting plant growth through symbiotic relationships.
