Abstract
The oxygen and nutritional requirements for acetylene reduction by Rhizobium japonicum and Rhizobium sp. in liquid culture are described. The optimal oxygen concentration was about 0.1% in the gas phase, which is lower than that of any other known aerobic nitrogen-fixing microorganism. these organisms are also unique in that nitrogenase synthesis is not repressed in the presence of ammonium chloride under certain cultural conditions, in contrast to other wild-type bacteria.This publication has 11 references indexed in Scilit:
