Korean Ginseng Center and Ginseng Genetic Resource Bank, Kyung Hee University, #1 Seocheon-dong, Giheung-gu Yongin-si, Gyeonggi-do 449-701, South Korea Correspondence Deok-Chun Yang dcyang{at}khu.ac.kr A Gram-positive, non-motile, pale-yellow, short rod-shaped bacterium, strain DCY26 T , was isolated from soil of a ginseng field in South Korea and was investigated to determine its taxonomic position. The organism grew optimally at 30–37 °C. The G+C content of its DNA was 65.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DCY26 T was related most closely to species of the genus Curtobacterium , in the family Microbacteriaceae . Strain DCY26 T showed highest 16S rRNA gene sequence similarity to Curtobacterium pusillum DSM 20527 T (96.3 %), Curtobacterium luteum DSM 20542 T (96.2 %), Curtobacterium flaccumfaciens LMG 3645 T (96.2 %), Curtobacterium citreum DSM 20528 T (96.1 %), Curtobacterium albidum DSM 20512 T (96.1 %) and Curtobacterium herbarum DSM 14013 T (95.3 %). The predominant menaquinone of strain DCY26 T was MK-9. Other chemotaxonomic data also supported the affiliation of strain DCY26 T to the genus Curtobacterium . On the basis of its phenotypic properties and phylogenetic distinctiveness, strain DCY26 T is considered to represent a novel species of the genus Curtobacterium , for which the name Curtobacterium ginsengisoli sp. nov. is proposed. The type strain is DCY26 T (=KCTC 13163 T =JCM 14773 T ). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain DCY26 T is EF587758 .
