Article Abstract

A Gram-strain-negative, strictly aerobic, rod-shaped, catalase-positive, oxidase-positive and pinkish beige colony-forming bacterial strain designated as BMJM1 was isolated from a marine sample collected from coastal water near Tongyeong, Republic of Korea. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that BMJM1 represents a member of the genus as it is closely related to KCTC 12794 (98.27%), DSM 24564 (97.98%), KCTC 32538 (97.91%), DSM 14336 (97.26%) and DSM 24565 (97.25%). Optimal growth occurred at 25-30°C, pH 7.0 and with 2% NaCl. Digital DNA-DNA hybridisation (dDDH) and average nucleotide identity (ANI) values between strain BMJM1 and the closely related species of the genus were below 40 and 90%, respectively, which are far below the thresholds to delineate a novel species. The predominant fatty acids (>10%) are summed feature 8 (Cω7 and/or Cω6) (68.4%) and Ciso E (11.6%). The major polar lipids were phosphatidylethanolamine and phospholipid. The major isoprenoid quinone was ubiquinone-10. The DNA G+C content was 64.0%. On the basis of the results of the polyphasic taxonomic characterisation, BMJM1 represents a novel species of the genus , for which the name is sp. nov. is proposed, with that type strain BMJM1 (= KCTC 92110 = GDMCC 1.2992).
