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