title: Jannaschia aquimarina sp. nov., isolated from seawater.
abstract: A Gram-negative, aerobic, non-motile rod, designated GSW-M26(T), was isolated from seawater from the southern coast of Korea. Strain GSW-M26(T) 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(T) fell within the cluster comprising the genus Jannaschia and clustered with Jannaschia seosinensis CL-SP26(T). The isolate exhibited the highest 16S rRNA gene sequence similarity (96.9%) with J. seosinensis CL-SP26(T) and 93.7-95.5% 16S rRNA gene sequence similarity with the other members of the genus Jannaschia. Strain GSW-M26(T) contained Q-10 as the predominant ubiquinone and C(18:1)ω7c and 11-methyl C(18:1)ω7c 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(T) could be differentiated from recognized members of the genus Jannaschia. On the basis of the data presented, strain GSW-M26(T) 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-M26(T) (=KCTC 23555(T) =CCUG 60899(T)).
