Abstract

A Gram-stain-negative, rod-shaped, aerobic, non-flagellated, chemoheterotrophic bacterium, designated IMCC14385, was isolated from surface seawater of the East Sea, Republic of Korea. The 16S rRNA gene sequence analysis indicated that IMCC14385 represented a member of the genus sharing 94.6–97.8 % similarities with species of the genus. Whole-genome sequencing of IMCC14385 revealed a genome size of 4.3 Mbp and DNA G+C content of 56.7 mol%. The genome of IMCC14385 shared an average nucleotide identity of 76.6 % and digital DNA–DNA hybridization value of 21.6 % with the genome of KCTC 23429. The genome encoded the complete poly--hydroxybutyrate biosynthesis pathway. The strain contained summed feature 8 (C 7 and/or C 6), summed feature 3 (C 7 and/or C 6) and C 8 as the predominant cellular fatty acids as well as ubiquinone-8 (Q-8) as the respiratory quinone. The polar lipids detected in the strain were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, five unidentified phospholipids, an unidentified aminolipid, an unidentified aminophospholipid and four unidentified lipids. On the basis of taxonomic data obtained in this study, it is suggested that IMCC14385 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is IMCC14385 (=KCTC 72520=NBRC 114072).
