WebbRhizobium: nitrogen fixing bacteria. Rhizobia are one of several group of bacteria capable of ‘fixing’ nitrogen, i.e. converting dinitrogen gas into ammonia and then into organic molecules such as amino acids. Because of this ability, nitrogen fixing bacteria are significant conduits between an extremely large pool of nitrogen in the ... WebbRhizobia reside within root nodules where they fix inert atmospheric di-nitrogen gas into forms that can be used by the plants. Hence, while in nature legumes plants can meet their entire N requirements from N fixation, we found that in hydroponic cultivation systems, provision of inorganic N helped the productivity. small shipping storage containers
