title: Jannaschia seohaensis sp. nov., isolated from a tidal flat sediment.
abstract: A Gram-negative, motile and pleomorphic bacterial strain, SMK-146(T), was isolated from a tidal flat sediment of the Yellow Sea, Korea, and its taxonomic position was investigated. Strain SMK-146(T) grew optimally at pH 7.0-8.0 and 30 degrees C. It contained Q-10 as the predominant ubiquinone and C(18 : 1)omega7c and 11-methyl C(18 : 1)omega7c 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-146(T) belongs to the genus Jannaschia. Strain SMK-146(T) 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-146(T) and Jannaschia seosinensis KCCM 42114(T), the closest phylogenetic neighbour, was 17 %. Differential phenotypic properties also revealed that strain SMK-146(T) differs from the recognized Jannaschia species. On the basis of phenotypic, phylogenetic and genetic data, strain SMK-146(T) represents a novel species of the genus Jannaschia, for which the name Jannaschia seohaensis sp. nov. is proposed. The type strain is SMK-146(T) (=KCTC 22172(T) =CCUG 55326(T)).
