title: Thiosulfate oxidation by a thermo-neutrophilic hydrogen-oxidizing bacterium, Hydrogenobacter thermophilus.
abstract: The thermo-neutrophilic hydrogen-oxidizing bacterium Hydrogenobacter thermophilus constitutively oxidizes thiosulfate. Soluble extracts of it showed temperature-dependent thiosulfate oxidation activity with an optimum at 60 degrees C. A gene cluster for sox (sulfur oxidation) is presumably responsible for this activity. Among the cluster, two tandemly coded soxA genes were uniquely found. These results suggest that the Sox system is widespread even in thermo-neutrophilic environments.
