Abstract

Strain DCY45 was isolated from soil of a ginseng field in Pocheon Province, Korea. Strain DCY45 was Gram-negative, oxidase- and catalase-positive, motile and rod-shaped and produced yellow pigments on R2A agar. The organism grew optimally at 30 °C and at pH 7.0. The GC content of the genomic DNA was 65.4 mol%. The predominant respiratory quinone was Q-8. The major fatty acids were iso-C 9, iso-C and iso-C. Phylogenetic analysis based on the 16S rRNA gene sequence was used to determine the taxonomic position of strain DCY45, which is most closely related to species of the genus , with similarity levels of 96.0–98.4 %; DNA–DNA relatedness with related strains was lower than 60 %. Strain DCY45 differed significantly from related type strains in phenotypic characteristics. On the basis of these phenotypic, genotypic and chemotaxonomic studies, strain DCY45 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DCY45 (=KCTC 22620 =JCM 16126).
