A thermophilic rod (strain SEBR 5268), isolated from an oil‐producing well, was identified as a Thermoanaerobacter strain that was phenotypically related to T. finnii . Both SEBR 5268 and T. finnii oxidized H 2 by reducing thiosulfate to sulfide using yeast extract as growth substrate. H 2 oxidation in the presence of thiosulfate was significant at the end of the exponential growth of SEBR 5268 and was maintained during the lysis phase. In the absence of thiosulfate, H 2 was inhibitory for both strains. The role of H 2 consumption by these bacteria is discussed with regard to their metabolism on organic compounds.
