abstract= A yellow-pigmented bacterium, designated strain GZJT-2T, was isolated from the stem of Hylomecon japonica (Thunb.) Prantl et Kündig collected from Taibai Mountain in Shaanxi Province, north-west China. Cells of strain GZJT-2T were Gram-reaction-negative, strictly aerobic, rod-shaped, non-spore-forming and non-motile. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain GZJT-2T was a member of the genus Sphingomonas, with sequence similarities of 92.1–96.9 % to type strains of recognized species of the genus Sphingomonas (92.1 % to Sphingomonas oligoaromativorans SY-6T and 96.9 % to Sphingomonas oligophenolica JCM 12082T). Strain GZJT-2T contained ubiquinone-10 (Q-10) as the predominant respiratory quinone and sym-homospermidine as the major polyamine. The major cellular fatty acids were summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C14 : 0 2-OH. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylcholine, sphingoglycolipid, four unidentified phospholipids, an unidentified aminolipid and four unidentified lipids were detected in the polar lipid profile. The DNA G+C content was 62.5 ± 0.3 mol%. On the basis of data from phenotypic, phylogenetic and DNA–DNA relatedness studies, strain GZJT-2T is considered to represent a novel species of the genus Sphingomonas, for which the name Sphingomonas hylomeconis sp. nov. is proposed. The type strain is GZJT-2T ( = CCTCC AB 2013304T = KCTC 42739T).,
