Abstract

A novel Gram-staining-negative, rod-shaped bacterium, designated DCY78(T), was isolated from soil of a ginseng field in Yeon-cheon province (38° 04' 00″ N 126° 57' 00″ E), Republic of Korea. The phylogenetic analysis based on 16S rRNA gene sequences showed that strain DCY78(T) belonged to the genus Epilithonimonas and was most closely related to Epilithonimonas lactis DSM 19921(T) (98.5 % sequence similarity) and Epilithonimonas tenax DSM 16811(T) (97.8 %). Growth occurred at 10-30 °C with an optimum temperature of 28 °C. The pH range for growth was pH 5.5-8.0. The major polar lipids were found to be phosphatidylethanolamine three unidentified amino lipids and one unidentified polar lipid. The only predominant quinone was MK-6. The major polyamines were sym-homospermidine and spermidine. The major fatty acids were summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c), iso-C15 : 0 and iso-C17 : 0 3-OH. The DNA G+C content was 37.9 mol%. On the basis of the phenotypic and genotypic analysis, the isolate is classified as representative of a novel species in the genus Epilithonimonas, for which the name Epilithonimonas ginsengisoli is proposed. The type strain is DCY78(T) ( = KCTC 32174(T) = JCM 19896(T)).
