Summary of "Litorimonas taeanensis gen. nov., sp. nov., isolated from beach sand of the Yellow Sea."

A heterotrophic, Gram-negative, prosthecate bacterium, designated strain G5T, was isolated from beach sand of Taean in South Korea. Cells were yellow-orange pigmented on agar plates and were straight to slightly curved aerobic motile rods with a single flagellum. The strain showed catalase- and oxidase-positive reactions. Growth was observed between 15 and 40 degrees C (optimum, 25-30 degrees C) and between pH 6.0 and 9.0 (optimum, pH 7.0-8.0). The major cellular fatty acids were C18:1&omega7c, C17:0, C16:0, 11- methyl C18:1omega7c, C17:1 omega8c and C17:1 omega6c. The polar lipid pattern indicated the presence of phosphatidylglycerol, monoglycosyldiglyceride, glucuronopyranosyldiglyceride and two unidentified glycolipids. The G+C content of the genomic DNA was 63.6 mol% and the major quinone was Q-10.Comparative 16S rRNA gene sequence analysis showed that strain G5T belonged to the Hellea, Robiginitomaculum and Hypomonas branch within the family Hyphomonadaceae. Among this group, strain G5T was most closely related to Hellea balneolensis 26III/A02/215T with 95.8 % 16S rRNA gene sequence similarity. On the basis of phenotypic, chemotaxonomic and molecular properties, strain G5T represents a novel genus of the family Hyphomonadaceae, for which the name Litorimonas taeanensis gen. nov., sp. nov. is proposed. The type strain is G5T (=KACC 13701T = DSM 22008T).
