Abstract

A Gram-negative, aerobic, non-motile rod, designated GSW-M26, was isolated from seawater from the southern coast of Korea. Strain GSW-M26 grew optimally at pH 7.0–8.0, at 30 °C and with 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain GSW-M26 fell within the cluster comprising the genus and clustered with CL-SP26. The isolate exhibited the highest 16S rRNA gene sequence similarity (96.9 %) with CL-SP26 and 93.7–95.5 % 16S rRNA gene sequence similarity with the other members of the genus . Strain GSW-M26 contained Q-10 as the predominant ubiquinone and Cω7 and 11-methyl Cω7 as the major fatty acids. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol and one unidentified aminolipid. The DNA G+C content was 66.4 mol%. Phenotypic characteristics demonstrated that strain GSW-M26 could be differentiated from recognized members of the genus . On the basis of the data presented, strain GSW-M26 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is GSW-M26 ( = KCTC 23555  = CCUG 60899).
