title: [Pathways of assimilation of carbon oxides in carboxydobacteria Seliberia carboxydohydrogena and Achromobacter carboxydus].
abstract: Assimilation products of 14C-bicarbonate and carbon-14C oxide were studied in two carboxydobacteria Seliberia carboxydohydrogena and Achromobacter carboxydus which differed in their ability for chemolithoautrophous growth in the presence of hydrogen. The dynamics and composition of labeled products formed upon assimilation of 14C-bicarbonate in the presence of unlabeled carbon oxide by the two organisms, the composition of products formed upon assimilation of 14CO by suspensions of S. carboxydohydrogena Z-1062 during 5 minutes, and the dynamics and composition of labeled assimilates of A. carboxydus Z-1171 after incubation in the presence of 14CO, were found to be consistent with those expected in the action of the reductive pentose phosphate Calvin cycle. The similarity of products formed upon assimilation of 14CO2 and 14CO suggests that CO is first oxidized to CO2, and only is assimilated.
