Abstract

A novel actinomycete strain, designated CFH S0054, was isolated from a soil sample collected from Xiaokongshan in Tengchong, Yunnan Province, in south-west PR China. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that strain CFH S0054 belonged to the genus . Based on the results of 16S rRNA gene sequence analysis, strain CFH S0054 was most closely related to IFM 0354 (98.3 %), NBRC 100128 (97.9 %), NBRC 14405 (97.9 %) and CFH S0067 (97.8 %). Strain CFH S0054 contained C, C ω9, C 10-methyl (TBSA) and summed feature 3 as major cellular fatty acids and MK-8 (H4ω-cycl) as the major respiratory quinone. The polar lipid profile included phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and unknown phospholipids. The cell wall contained -diaminopimelic acid, and the whole-cell hydrolysates were arabinose, galactose, glucose, fructose, ribose and mannose. The genome of strain CFH S0054 was 7.9 Mbp with a G+C content of 68.4 mol%, the average nucleotide identity (ANI) values between strain CFH S0054 and IFM0354 were low (ANIm<87.7 % and ANIb=84.1 %). On the basis of phylogenetic, physiological and chemotaxonomic data, strain CFHS0054 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed, The type strain is CFH S0054 (DSM 46763=JCM 30082).
