Abstract

Summary: Cultures of grown in the absence of a source of fixed nitrogen reduced acetylene to ethylene suggesting the presence of nitrogenase. This presumptive evidence has now been substantiated by the demonstration of the enrichment of N in the protein of the organism when grown under N. The possibility that was being grown in association with other nitrogen-fixing organisms was eliminated by the use of cultures derived from colonies whose development had been observed from single organisms.
