- Abstract
The type strain DCY99 was isolated from soil collected from a ginseng field in Hwacheon, Republic of Korea. Strain DCY99 is Gram-negative, non-spore forming, motile, rod-shaped, and strictly aerobic. The bacteria grow optimally at 25-30 °C and pH 6.0-6.5. Phylogenetically, strain DCY99 is most closely related to Sphingomonas oligophenolica JCM 12082, followed by Sphingomonas asaccharolytica KCTC 2825, Sphingomonas mali KCTC 2826, Sphingomonas cynarae JCM17498, Sphingomonas pruni KCTC 2824, and Sphingomonas glacialis DSM 22294. The DNA-DNA relatedness between strain DCY99 and S. oligophenolica JCM 12082 was 15.6 ± 0.4 %, and the DNA G+C content of strain DCY99 was 64.4 mol%. An isoprenoid quinone was detected and identified as ubiquinone Q-10, and sym-homospermidine was identified as the major polyamine of DCY99. The major polar lipids were identified as sphingoglycolipid, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, and phosphatidylcholine. C2OH, C, and summed feature 8 (C ω7 c:/C ω6 c) were identified as the major fatty acids present in DCY99. The results of physiological and biochemical tests allowed strain DCY99 to be differentiated phenotypically from other recognized species belonging to the genus Sphingomonas. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Sphingomonas panacis sp. nov. is proposed with the type strain designated as DCY99 (=JCM 30806 =KCTC 42347).
