Microbiology of Soils The groups of symbiotic bacteria, which have the ability to fix nitrogen All of these these bacteria are from the genus, Rhizobium 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 All of these these bacteria are from the genus, Rhizobium 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 ANSWER DOWNLOAD EXAMIANS APP
