title: Brachybacterium ginsengisoli sp. nov., isolated from soil of a ginseng field.
abstract: A novel Gram-staining-positive, aerobic bacterium, designed DCY80(T), was isolated from soil of a ginseng field in the Republic of Korea. 16S rRNA gene sequence analysis revealed that strain DCY80(T) belonged to the genus Brachybacterium (95.8-98.2 % similarity) and was most closely related to Brachybacterium faecium DSM 4810(T) (98.2 %). Colonies were circular, entire, low-convex, opaque and 0.5-1.0 mm in diameter after growth for 2 days on TSA at 30 °C. Growth occurred at 4-34 °C (optimum, 25 °C), at pH 5.0-10.0 (optimum, pH 6.5-7.0) and in the presence of 0-7.0 % NaCl. Strain DCY80(T) produced siderophores and was sensitive to penicillin G, erythromycin, cefazolin, oleandomycin, ceftazidime, vancomycin, tetracycline, novobiocin, carbamicillin, rifampicin and neomycin. The DNA G+C content was 71.0 mol%. Levels of DNA-DNA relatedness between strain DCY80(T) and B. faecium DSM 4810(T), B. paraconglomeratum KCTC 9916(T), B. saurashtrense DSM 23186(T) and B. conglomeratum KCTC 9915(T) were 46.9±0.5, 28.9±0.6, 20.4±0.9 and 17.3±0.4 %, respectively. The cell-wall peptidoglycan of strain DCY80(T) contained meso-diaminopimelic acid as the diagnostic diamino acid. The menaquinones were MK-7 (85.8 %) and MK-8 (14.2 %). The major cellular fatty acids were anteiso-C15 : 0 (69.1 %) and anteiso-C17 : 0 (12.2 %). Phosphatidylglycerol, diphosphatidylglycerol, an unidentified glycolipid, two unidentified phospholipids and five unidentified polar lipids were found. On the basis of our phenotypic and genotypic analyses, strain DCY80(T) represents a novel species of the genus Brachybacterium, for which the name Brachybacterium ginsengisoli sp. nov. is proposed (type strain DCY80(T) = KCTC 29226(T) = JCM 19356(T)).
