Abstract:
A novel, thermophilic, obligately chemolithoautotrophic, sulfur/thiosulfate-oxidizing bacterium was isolated from subsurface geothermal aquifer water (temperature approximately 70 °C) in the Hishikari gold mine, Japan. Cells of the isolate, designated strain C55 T , were motile, straight rods with a single polar flagellum. Growth was observed at temperatures between 35 and 62 °C (optimum 50–55 °C; 60 min doubling time) and pH between 5·2 and 7·7 (optimum pH 6·5–7·0). High growth rate of strain C55 T was observed on either thiosulfate or elemental sulfur as a sole energy source, with molecular oxygen as the only electron acceptor. None of the organic compounds tested supported or stimulated growth of strain C55 T . The G+C content of the genomic DNA was 66·9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain C55 T was affiliated to the β - Proteobacteria , but was distantly related to recognized genera. On the basis of its physiological and molecular properties, strain C55 T (=JCM12421 T =DSM 16629 T =ATCC BAA-941 T ) is proposed as the type strain of Thiobacter subterraneus gen. nov., sp. nov.
