Terrestrial mud volcanoes (TMVs), surface expressions of a deep-subterranean sedimentary volcanism, are widespread throughout the world. The methane and sulfur cycles are recognized as the most important biogeochemical cycles in these environments. Only few anaerobic bacterial strains were recovered from TMVs. We have isolated a novel sulfate-reducing bacterium (strain SB368) from TMV located at Taman Peninsula, Russia. Optimum growth of strain SB368 was observed at 30 °C, pH 8.0 and 1% NaCl. Strain SB368 utilized lactate, pyruvate and fumarate in the presence of sulfate, sulfite or thiosulfate. Growth with molecular hydrogen was observed only in the presence of acetate. Fermentative growth occurred on pyruvate. Phylogenetic analysis revealed that strain SB368 belongs to the genus Pseudodesulfovibrio but is distinct from all described species. Based on its genomic and phenotypic properties, a new species, Pseudodesulfovibrio pelocollis sp. nov. is proposed with strain SB368 (= DSM 111087 = VKM B-3585) as a type strain.
