A Gram-negative bacterium, designated DCY13(T), was isolated from soil of a ginseng field in South Korea. Comparative analysis of 16S rRNA gene sequences showed that strain DCY13(T) shared the highest sequence similarity (95.0%) with Sediminibacterium salmoneum NBRC 103935(T) and 87.6-91.4% sequence similarity with other members of the family Chitinophagaceae. Cells were non-spore-forming rods, catalase- and oxidase-positive, motile by gliding and facultatively anaerobic. The only respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were iso-C-17:0 3-OH, iso-C-15:0 and iso-C-15:1 G. The G+C content of the genomic DNA was 47.5 +/- 1.0 mol%. In addition to phosphatidylethanolamine, the major polar lipids were two unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The major cell-wall sugars were ribose, xylose and galactose. It is proposed that strain DCY13(T) represents a novel species in the genus Sediminibacterium, for which the name Sediminibacterium ginsengisoli sp. nov. is proposed. The type strain is DCY13(T) (=KCTC 12833(T) = JCM 15794(T) = DSM 22335(T)). Emended descriptions of the genus Sediminibacterium and of Sediminibacterium salmoneum are also proposed.
