Abstract

Strain LHWP2, a novel, aerobic, budding, motile and ovoid bacterium belonging to the phylum , was isolated from a dead ark clam () from the south coast of Korea. Strain LHWP2 grew optimally at 30 °C, in the presence of 4 % (w/v) NaCl, and at pH 7. The predominant cellular fatty acids were C, Cω7 and/or Cω6 (summed feature 8) and Cω9. The major isoprenoid quinone was menaquinone-6 (MK-6). The dominant polar lipid was identified as phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain was most closely related to DSM 3645, with a 16S rRNA gene sequence similarity of 94.1 %. The genomic DNA G+C content of strain LHWP2 was 49.5 mol%. Strain LHWP2 was distinguished from DSM 3645 based on its optimum salinity, acid production from substrates, assimilation of substrates and DNA G+C content. Overall, these phenotypic, genotypic and phylogenetic data suggest that strain LHWP2 should be classified as a novel species belonging to the genus , for which the name sp. nov. is proposed. The type strain is LHWP2 ( = KACC 15559 = JCM 17758).
