A Gram-negative, non-motile, rod-shaped bacterium, strain SS011B1-20, was isolated from sediments of the South China Sea. Growth occurred at NaCl concentrations between 0 and 10 % and at temperatures between 10 and 37 °C. Strain SS011B1-20 contained Q-10 as the major respiratory quinone and C 7 (81.2 %), C (7.0 %) and C methyl (4.3 %) as the predominant fatty acids. The G+C content of the genomic DNA was 64.7 mol%. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain SS011B1-20 belonged to a clade within the genus in the , the highest sequence similarities being found with respect to (96.3 %) and with (94.9 %). Strain SS011B1-20 could be clearly distinguished from other species on the basis of the genotypic, phenotypic and phylogenetic data. Thus, it is proposed that strain SS011B1-20 represents a novel species of the genus , with the name sp. nov. The type strain is SS011B1-20 (=LMG 23508=CGMCC 1.6293).
