Curtobacterium ginsengisoli sp. nov., isolated from soil of a ginseng field

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).
