| Abstract |
Strain U15T, rod-shaped, catalase and oxidase positive, non-motile, hot pink pigmented, Gram-negative bacterium, was isolated from soil of Udo port, Udo Island, South Korea. Growth was observed at 10-48 °C, pH 6-11, and 0% (w/v) NaCl. Optimum growth conditions are 30-40 °C, pH 7-10, and 0% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA sequences showed that strain U15T forms a distinct clade with type strains of the family Cytophagaceae, with similarities below 89%. The major polar lipids are phosphatidylethanolamine and phosphatidylserine. Strain U15T was found to contain MK-7 as the only menaquinone, and iso-C15:0, C16:1ω5c, iso-C17:0 3-OH and summed feature 3 (comprising C16:1ω7c and/or C16:1ω6c) as the major fatty acids (> 10%). The DNA G + C content of strain U15T was determined to be 54.3 mol%. Based on the phylogenetic, phenotypic characteristics and chemotaxonomic analysis data, strain U15T (= KCTC 62116T = JCM 32361T) should be classified as representing a novel species of a novel genus within the family Cytophagaceae for which the name Tellurirhabdus rosea gen. nov., sp. nov., is proposed.
