Abstract

A novel, Gram-stain-negative, rod-shaped bacterial strain, designated as DCY109, was isolated from the rhizosphere of rusty mountain ginseng root located on Hwacheon mountain of Gangwon province, South Korea. 16S rRNA gene sequence analysis revealed that strain DCY109 belonged to the genus and was related closely to KACC 15042(98.2 % similarity), DSM 1986 (96.9 %) and KCTC 12206 (96.7 %). The predominant isoprenoid quinone was ubiquinone (Q-10) and the DNA G+C content was 66.9 mol%. The major polar lipids were phosphatidylglycerol, an unidentified glycolipid and an unidentified lipid. The major fatty acids (>10 %) were C, summed feature 3 (which comprised C 7 and/or C 6) and summed feature 8 (which comprised C 7 and/or C 6). Mean DNA–DNA relatedness between strain DCY109 and its closest relative, KACC 15042, was 15.1±3.9 %. Based on the physiological, biochemical, chemotaxonomic and genetic analyses, strain DCY109 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DCY109 (=KCTC 42749=JCM 31045).
