Abstract A novel strictly anaerobic thermophilic heterotrophic bacterium, strain SLHLJ1(T), was isolated from a Pacific hydrothermal sediment. Cells were Gram-negative coccobacilli (approximately 1.0 × 0.6 μm) with a toga. It grew at temperatures between 33 and 78 °C (optimum 70 °C). Elemental sulphur and L-cystine stimulated its growth. It contained C16:0, C16:1 ω11c, C18:0 and C18:1 ω9c as major fatty acids (>5%), 3 phospholipids and 2 glycolipids as polar lipids. Its DNA G+C content was 43.7 mol%. Phylogenetic analyses based on 16S rRNA gene sequences placed strain SLHLJ1(T) within the family Thermotogaceae. The novel isolate was most closely related to Kosmotoga arenicorallina (97.93 % 16S rRNA gene sequence similarity), K. olearia (92.43%) and K. shengliensis (92.17 %). On the basis of phenotypic, chemotaxonomic and phylogenetic comparisons with its closest relatives, we propose its assignment to a novel species of the genus Kosmotoga. The name Kosmotoga pacifica sp. nov. is proposed with strain SLHLJ1(T) (=DSM 26965(T) = JCM 19180(T) = UBOCC 3254(T)) as the type species.
