Abstract
A Gram-negative, non-motile, pleomorphic bacterial strain, designated SMK-142T, was isolated from a tidal flat of the Yellow Sea, Korea, and was subjected to a polyphasic taxonomic study. Strain SMK-142T grew optimally at pH 7.0-8.0, 25 °C and in the presence of 2% (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SMK-142T clustered with Lutibacter litoralis with which it exhibited a 16S rRNA gene sequence similarity value of 91.2 %. This cluster joined the clade comprising the genera Tenacibaculum and Polaribacter at a high bootstrap resampling value. Strain SMK-142T contained MK-6 as the predominant menaquinone and iso-C15:0, iso-C15:1 and iso-C17:0 3-OH as the major fatty acids. The DNA G+C content was 37.2 mol%. Strain SMK-142T was differentiated from three phylogenetically related genera, Lutibacter, Tenacibaculum and Polaribacter, on the basis of low 16S rRNA gene sequence similarity values and differences in fatty acid profiles and in some phenotypic properties. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain SMK-142T represents a novel genus and species for which the name Aestuariicola saemankumensis gen. nov., sp. nov. is proposed (phylum Bacteroidetes, family Flavobacteriaceae). The type strain of the type species, Aestuariicola saemankumensis sp. nov., is SMK-142T (=KCTC 22171T=CCUG 55329T).
