abstract= A novel thermophilic, obligately anaerobic bacterium, strain Cel2fT, was isolated from a cellulolytic community enriched from coastal marine sediment. Cells were Gram-stain-negative, non-motile, non-spore-forming and rod-shaped. Optimal growth temperature and pH of strain Cel2fT were 55 °C and pH 7.0, respectively. NaCl was essential for the growth of strain Cel2fT and the strain showed enhanced growth in the presence of sea salt; the optimum sea salt concentration for growth was 7 % (w/v). Thiosulfate, sulfate and sulfite were potential electron acceptors. The major fatty acids of strain Cel2fT were iso-C15 : 0, C16 : 0, and C18 : 0. Polar lipid analysis indicated the presence of phosphatidylethanolamine and phosphatidylglycerol. Strain Cel2fT contained menaquinone MK-7 as the isoprenoid quinone, and the DNA G+C content was 31.3 mol%. Phylogenetic analysis revealed that the nearest relative of strain Cel2fT was Brassicibacter mesophilus BMT with 93.8 % 16S rRNA gene sequence similarity. Based on phenotypic, chemotaxonomic and phylogenetic characteristics, strain Cel2fT represents a novel species of genus Brassicibacter, for which the name Brassicibacter thermophilus sp. nov. is proposed. The type strain is Cel2fT ( = JCM 30480T = CGMCC 1.5200T).,
