Abstract 

A Gram-negative, motile and pleomorphic bacterial strain, SMK-146T, was isolated from a tidal flat sediment of the Yellow Sea, Korea, and its taxonomic position was investigated. Strain SMK-146T grew optimally at pH 7.0-8.0 and 30 °C. It 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 and phosphatidylethanolamine. The DNA G+C content was 68.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SMK-146T belongs to the genus Jannaschia. Strain SMK-146T exhibited 16S rRNA gene sequence similarity values of 95.3-97.0% to the type strains of the five recognized Jannaschia species. The mean DNA-DNA relatedness value between strain SMK-146T and Jannaschia seosinensis KCCM 42114T, the closest phylogenetic neighbour, was 17 %. Differential phenotypic properties also revealed that strain SMK-146T differs from the recognized Jannaschia species. On the basis of phenotypic, phylogenetic and genetic data, strain SMK-146T represents a novel species of the genus Jannaschia, for which the name Jannaschia seohaensis sp. nov. is proposed. The type strain is SMK-146T (=KCTC 22172T =CCUG 55326T).
