abstract= A novel Gram-stain-negative, flagellated, rod-shaped, yellow-pigmented aerobic bacterium, strain SA925T, that is capable of degrading 1-methylphenanthrene was isolated from oil-polluted soil collected from a refinery located in Guangzhou, China. Phylogenetic analysis based on the 16S rRNA gene sequence demonstrated that strain SA925T belongs to the genus Novosphingobium and is evolutionarily close to the type strains of Novosphingobium gossypii (98.5 % similarity), Novosphingobium panipatense (98.2 %), Novosphingobium mathurense (98.0 %) and Novosphingobium pentaromativorans (96.5 %). The G+C content of the genomic DNA was 60.2 mol%. DNA–DNA hybridization experiments between strain SA925T and the closest strain, Novosphingobium gossypii JM-1396T, revealed a low level of relatedness (35.5 %). Strain SA925T grew at 10–35 °C, at pH 6.0–8.0 and in the presence of 0–4 % (w/v) NaCl. The major fatty acids were C18 : 1 ω7c, C16 : 0 and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). The polar lipid profiles mainly consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidyldimethylethanolamine, phosphatidylethanolamine and sphingoglycolipid (the characteristic polar lipid). The predominant ubiquinone was Q-10. The major polyamine was spermidine. Based on the phylogenetic, phenotypic and physiological characteristics, strain SA925T was considered to represent a novel species of the genus Novosphingobium , for which the name Novosphingobium guangzhouense sp. nov. is proposed. The type strain is SA925T (=DSM 32207T=GDMCC 1.1110T).,
