Jannaschia seohaensis sp. nov., isolated from a tidal flat sediment Yoon, Jung-Hoon and Kang, So-Jung and Park, Sooyeon and Oh, Ki-Hoon and Oh, Tae-Kwang,, 60, 191-195 (2010), doi = https://doi.org/10.1099/ijs.0.011270-0, publicationName = Microbiology Society, issn = 1466-5026, 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 : 1 ω7c and 11-methyl C18 : 1 ω7c 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)., language=, type=
