gen. nov., sp. nov., isolated from seawater Free

Abstract

A novel actinobacterial strain was isolated from a seawater sample collected on Mara Island, Jeju, Republic of Korea. Cells of this organism were aerobic, Gram-positive, non-spore-forming, non-motile cocci that occurred singly or in pairs. Colonies were circular, smooth, convex and white–cream in colour. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family and formed a monophyletic clade between the type strains of (96.8 % similarity) and (95.2 % similarity). The cell-wall peptidoglycan contained -lysine, alanine, aspartic acid, glutamic acid, glycine and serine, indicating that the isolate possessed peptidoglycan type A4α. The whole-cell sugars were galactose, glucose, mannose, xylose, arabinose, ribose and rhamnose. The major menaquinone was MK-8(H). The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, an unknown phospholipid and five unknown lipids. The cellular fatty acid profile was represented by large amounts of iso-methyl branched and monounsaturated iso- and anteiso-methyl branched acids, along with the presence of a diagnostic 10-methyl acid. The G+C content of the DNA was 71 mol%. On the basis of data from polyphasic analyses presented here, strain MSW-24 is considered to represent a novel species of a new genus in the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is MSW-24 ( = KCTC 19485 = DSM 21415).
