Abstract

A novel bacterial strain, designated DCY54, was isolated from a field cultivated with ginseng in Yongin, Republic of Korea. Cells were Gram-reaction-negative, yellow-pigmented, rod-shaped, non-spore-forming, and strictly aerobic. They were motile by gliding and produced flexirubin-type pigments. Growth occurred optimally at 25–30 °C, at pH 5.0–7.0 and in the presence of 0–1 % NaCl. The 16S rRNA sequence analysis demonstrated that strain DCY54 was most closely related to EMB117 (96.9 %). The only isoprenoid quinone of strain DCY 54 was menaquinone-6 (MK-6) and the major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The major cellular fatty acids (>15 %) were iso-C, summed feature 3 (comprising Cω7 and/or iso-C 2-OH) and C. The DNA G+C content was 33.3 mol%. Phylogenetic inference and phenotypic data supported affiliation of strain DCY54 to the genus . Several physiological and biochemical tests differentiated strain DCY54 from the species of the genus with validly published names. On the basis of data from a polyphasic study, strain DCY54 represents a novel species of the genus for which the name sp. nov. is proposed. The type strain is DCY54 ( = KCTC 23318 = JCM 17336).
