Abstract
A Gram-negative, aerobic, non-motile rod, designated GSW-M26T, was isolated from seawater from the southern coast of Korea. Strain GSW-M26T 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-M26T fell within the cluster comprising the genus Jannaschia and clustered with Jannaschia seosinensis CL-SP26T. The isolate exhibited the highest 16S rRNA gene sequence similarity (96.9 %) with J. seosinensis CL-SP26T and 93.7–95.5 % 16S rRNA gene sequence similarity with the other members of the genus Jannaschia . Strain GSW-M26T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c and 11-methyl C18 : 1ω7c 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-M26T could be differentiated from recognized members of the genus Jannaschia . On the basis of the data presented, strain GSW-M26T is considered to represent a novel species of the genus Jannaschia , for which the name Jannaschia aquimarina sp. nov. is proposed. The type strain is GSW-M26T ( = KCTC 23555T = CCUG 60899T).
