Abstract

Summary: Four strains of the thermophilic phototrophic green bacterium were tested for nitrogenase activity under a variety of nutritional conditions consistent with nitrogenase derepression in anoxygenic photosynthetic bacteria. Although all strains of could grow with various amino acids as sole nitrogen sources, no growth on N was observed; acetylene reduction was undetectable in cells grown under any nutritional conditions. The inability of to fix N is discussed in connection with its thermophilic character.
