Nitrogen-fixing bacterium
WebBiological nitrogen fixation (BNF), discovered by Beijerinck in 1901 (Beijerinck 1901), is carried out by a specialized group of prokaryotes. These organisms utilize the enzyme nitrogenase to ... WebThis is a cross-section of a root nodule formed by the nitrogen-fixing bacteria rhizobium in symbiosis with a plant from the legume family. Within the nodule, bacteria convert atmospheric nitrogen into a plant-available form. Several key minerals drive this vital process. 14 Apr 2024 16:23:18
