| Abstract |
A novel, Gram-stain-negative, rod-shaped bacterial strain, designated as DCY109T, 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 DCY109T belonged to the genus Phenylobacterium and was related closely to Phenylobacterium muchangponense KACC 15042T (98.2 % similarity), Phenylobacterium immobile DSM 1986T (96.9 %) and Phenylobacterium koreense KCTC 12206T (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 C16 : 0, summed feature 3 (which comprised C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 8 (which comprised C18 : 1ω7c and/or C18 : 1ω6c). Mean DNA-DNA relatedness between strain DCY109T and its closest relative, P. muchangponense KACC 15042T, was 15.1±3.9 %. Based on the physiological, biochemical, chemotaxonomic and genetic analyses, strain DCY109T is considered to represent a novel species of the genus Phenylobacterium, for which the name Phenylobacterium panacis sp. nov. is proposed. The type strain is DCY109T (=KCTC 42749T=JCM 31045T).
