A novel bacterium, designated CAU 1612 , was isolated from coastal sediment sampled in the Republic of Korea. Cells of the strain were Gram-stain-negative, rod-shaped and motile. Optimum growth occurred at 30 °C, at pH 7.0 and with 1.0 % (w/v) NaCl. Based on 16S rRNA gene sequences, phylogenetic analysis revealed that strain CAU 1612 belonged to the genus and showed highest similarity to ' ' JCM 33810 (98.5 %), followed by KCTC 32476 (97.7 %), KCTC 12842 (96.0 %), LMG 23452 (95.5 %), KCTC 52846 (95.5 %) and KCTC 12842 (95.4 %). The average nucleotide identity and digital DNA-DNA hybridization values of strain CAU 1612 were estimated to be 68.5-81.7 % and ≤23.7 %, respectively, to members of the genus . The DNA G+C content was 54.1 mol%. The major cellular fatty acids (>10 %) were C , C cyclo 8 and summed feature 8 (C 7 and/or C 6 ). The major menaquinone was Q-10 and the predominant polar lipids were phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. On the basis of taxonomic evidence, strain CAU 1612 represents a novel species, for which the name sp. nov. is proposed. The type strain is CAU 1612 (=KCTC 82427 =MCCC 1K06082 ).
