Abstract
Thermoanaerobacter (T.) brockii, T. ethanolicus, andT. thermohydrosulfuricus were tested for their capacities to oxidize H2 in the presence of thiosulfate.T. brockii oxidized H2 actively, whileT. ethanolicus andT. thermohydrosulfuricus oxidized it poorly. At the end of the exponential growth, H2 was oxidized byT. brockii in the presence of an energy source and thiosulfate. This oxidative process improved the growth ofT. brockii. Thermoanaerobacter species could be divided into two groups with regard to their H2 metabolism in the presence of thiosulfate. Thiosulfate reduction by species of the genusThermoanaerobacter is of significance in mineralizing organic matter in thermophilic environments.
