A novel sulfate-reducing bacterium (strain JS1) was isolated from lake Pangong, a salt-water lake situated in the Himalayas of Leh District, Jammu and Kashmir, India. Cells of strain JS1 are Gram-negative, vibriod, motile by means of single polar flagellum, contain desulfoviridin, are catalase-positive and can hydrolyse starch. Strain JS1 grew optimally at pH 8.5–9.0 and at temperatures ranging from 10 to 50 °C (optimum 28–30 °C). Chemo-organoheterotrophy was the only growth mode of strain JS1 and was possible on a wide range of organic compounds. Sulfate alone but not sulfite, thiosulfate, elemental sulfur, nitrite or nitrate was used as electron acceptor. It has no requirement for NaCl but can tolerate up to 2 % NaCl (w/v). -Aminobenzoate is a required growth factor. The 16S rRNA gene sequence of the bacterium demonstrated similarity between strain JS1 and the members of the genus . The position of strain JS1 within the phylogenetic tree indicated that it clustered closely with DSM 10141 (89.85 % sequence similarity). On the basis of phenotypic and molecular genetic evidence, it is proposed that strain JS1 be classified as a novel species of the genus of the family , with the species name sp. nov. The type strain of the species is JS1 (=JCM 14597=KCTC 5573=DSM 19430).
