sp. nov., isolated from seawater, reclassification of as comb. nov. and emended description of the genus Hwang 2009 Free

Abstract

A Gram-stain-negative, non-motile, non-spore-forming, aerobic, rod-shaped bacterial strain, designated DPG-28, was isolated from seawater on the southern coast of Korea. Strain DPG-28 grew optimally at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DPG-28 formed a coherent cluster with members of the genera and , with which it exhibited sequence similarity values of 97.8–98.5 %. The DNA G+C content of strain DPG-28 was 65.1 mol%. The predominant ubiquinone of strain DPG-28 was ubiquinone-10 (Q-10), consistent with data for the genera and . The cellular fatty acid profiles of strain DPG-28 and the type strains of , and were essentially similar in that the common predominant fatty acid was Cω7. Major polar lipids found in strain DPG-28 and the type strains of , and were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified aminolipid. From these data, it is proposed that be reclassified as a member of the genus , for which the name comb. nov. is proposed, with the type strain SMK-114 ( = CCUG 57612  = KCTC 22632), and that strain DPG-28 be classified in the genus . Differential phenotypic properties and genetic distinctiveness of strain DPG-28 demonstrated that this strain is distinguishable from , and . On the basis of the data presented, strain DPG-28 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DPG-28 ( = KCTC 23421  = CCUG 60522). An emended description of the genus is also provided.
