A Gram-positive, non-spore-forming, rod-shaped, motile bacterium, designated strain DCY22, was isolated from soil of a ginseng field in South Korea and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain DCY22 belonged within the family , and highest levels of sequence similarity were found with 1-19 (96.8 %), ST-26 (96.0 %), ST-50 (95.9 %), ST-74 (95.5 %), PPLB (94.0 %) and DSM 20308 (93.8 %). Chemotaxonomic investigations revealed that strain DCY22 possessed menaquinone MK-9, a common feature of members of the genus . Predominant fatty acids were unknown ECL 13.961 (45.81 %), 17 : 0 anteiso (23.46 %), 18 : 0 iso (15.42 %) and unknown ECL 14.966 (8.70 %). The results of physiological and biochemical tests clearly demonstrated that strain DCY22 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DCY22 (=KCTC 13155=JCM 14841).
