The primary steps of N2, ammonia and nitrate metabolism in Klebsiella pneumoniae grown in a continuous culture are regulated by the kind and supply of the nitrogenous compound. Cultures growing on N2 as the only nitrogen source have high activities of nitrogenase, unadenylated glutamine synthetase a

An enrichment method for nitrogen fixing hydrogen bacteria is described. The procedure invariably resulted in the isolation of yellow-pigmented coryneform bacterial strains assigned to Corynebacterium autotrophicum. The procedure included a serial transfer in an ammonium-free mineral liquid medium u
Addition of ammonium salts to N 2 fixing continuous cultures of Clostridium pasteurianum caused immediate stop of nitrogenase synthesis, while the levels of glutamine synthetase, glutamate dehydrogenase and asparagine synthetase remained constant. No evidence for an interconversion of the glutamine
