Hamilton , I. R. (University of Wisconsin, Madison), R. H.Burris, P. W. Wilson, and C. H. Wang . Pyruvate metabolism and carbon dioxide assimilation by anAchromobacter species. J. Bacteriol.89: 647–653. 1965.—Carbon dioxide fixation by washed whole cells ofAchromobacter N4-B has been observed during anaerobic pyruvate metabolism with both nitrogen- and NH4 + -grown cells. Labeled sodium bicarbonate-C14 was assimilated into cells by a mechanism requiring pyruvate under conditions of nitrogen fixation, nitrogenase induction, and assimilation of NH4 + . Of the assimilated radioactivity, 89% appeared in six amino acids and two ninhydrin-positive unknown compounds, with the distribution of the label essentially independent of the nitrogen nutritional state of the organism. Aspartic and glutamic acids were the most highly labeled, with lesser amounts in glycine, alanine, ornithine, arginine, and the unknowns. All of the radioactivity extracted from these cells by ethanol-boiling water appeared in a protein fraction precipitated by 20% trichloroacetic acid. Radiorespirometric experiments with individually labeled pyruvate substrates demonstrated the preferential decarboxylation of the C-1 of pyruvate by this organism in a flowing helium gas phase. This decarboxylation was almost completely inhibited by using flowing nitrogen in place of helium; the addition of 0.5% CO2 to the flowing nitrogen prevented inhibition and allowed 70% of the expected CO2 evolution. These results, coupled with those from growth experiments, indicate a carbon dioxide requirement for anaerobic growth and pyruvate metabolism, which appears to be coupled to the formation of protein precursors.
