| Abstract |
A novel mesophilic sulfur- and thiosulfate-oxidizing bacterium, strain 42BKTT, was isolated from the gas-bubbling sediment at the Iheya North hydrothermal system in the mid-Okinawa Trough, Japan. The isolate was a Gram-negative, non-motile and coccoid to oval-shaped bacterium. Growth was observed at 10-40 degrees C (optimum 28-30 degrees C) and in the pH range 5.0-9.0 (optimum 6.5-7.0). Strain 42BKTT grew chemolithoautotrophically with elemental sulfur or thiosulfate as a sole electron donor and oxygen (optimum 5 % in gas phase) or nitrate as an electron acceptor. The G + C content of the genomic DNA was 48.0 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the isolate belonged to the previously uncultivated Group F within the epsilon-Proteobacteria, which includes phylotypes of vent epibiont and environmental sequences from global deep-sea cold seep and hydrothermal vent fields. On the basis of the physiological and molecular characteristics of this isolate, the type species of a novel genus, Sulfurovum lithotrophicum gen. nov., sp. nov., is proposed. The type strain is 42BKTT (= ATCC BAA-797T = JCM 12117T). |
