Microbiology of Soils The groups of symbiotic bacteria, which have the ability to fix nitrogen derive their food and minerals from the legume, and in turn they supply the legume with some or all of its nitrogen these bacteria are from the genus, Rhizobium All of these grow together for a mutual benefit is called symbiosis and so these bacteria are called symbiotic nitrogen-fixing bacteria derive their food and minerals from the legume, and in turn they supply the legume with some or all of its nitrogen these bacteria are from the genus, Rhizobium All of these grow together for a mutual benefit is called symbiosis and so these bacteria are called symbiotic nitrogen-fixing bacteria ANSWER DOWNLOAD EXAMIANS APP
