The nitrogenase activity of a filamentous phototrophic green bacterium


, : The nitrogenase activity of a filamentous phototrophic green bacterium. Mikrobiologiya 58(3): 520-521

A mesophilic filamentous green bacterium was isolated and shown to be similar in many properties to the earlier described species Oscillochloris trichoides. The strain was found to be capable of molecular nitrogen fixation, which had not been reported for other multicellular green bacteria. The highest nitrogenase activity was recorded for the strain Dg 6 grown in media with glycine, asparagine or in the atmosphere of molecular nitrogen. No nitrogenase acitivty was detected in different strains of the thermophilic filamentous green bacterium Chloroflexus aurantiacus irrespective of their growth conditions.
