Аннотация: Summary. A thermophilic, anaerobic, chemolithoautotrophic bacterium, strain SH388T, was isolated from a shallow submarine hydrothermal vent (Kuril Islands, Russia). Cells of strain SH388T were Gram-negative short rods, 0.2-0.4 µm in diameter and 1.0-2.5 µm in length, motile with flagella. The temperature range for growth was 25-58oC (optimum 50oC), and the pH range for growth was 5.0-7.0 (optimum 6.0-6.5). Growth of strain SH388T was observed in the presence of NaCl concentrations ranging from 0.5 to 4.0% (w/v) (optimum 2.0-2.5%). The strain grew chemolithoautotrophically with molecular hydrogen as electron donor, sodium sulfite as electron acceptor and bicarbonate/CO2 as a carbon source. It was also able to grow by disproportionation of sulfite and elemental sulfur but not thiosulfate. Sulfate, Fe(III) or nitrate were not used as an electron acceptors either with H2 or organic electron donors. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the class Deltaproteobacteria and was most closely related to Dissulfuribacter thermophilus and Dissulfurimicrobium hydrothermale (91.6% and 90.4% sequence similarity). On the basis of its physiological properties and results of phylogenetic analyses, strain SH388T is considered to represent a novel species of a new genus, for which the name Dissulfurirhabdus thermomarina gen. nov., sp. nov. is proposed. The type strain of species is SH388T= (DSM 100025T=VKM B-2960T). It is a first thermophilic disproportionator of sulfur compounds isolated from a shallow sea environment.
