A polyphasic taxonomic study was undertaken to establish the status of a novel bacterium, designated strain WHSC-8T, which was isolated from soil of Hengshui Lake Wetland Reserve in Hebei province, northern China. Colonies of this strain were yellow and cells were rod-shaped, polar-flagellated and obligately aerobic, exhibiting negative Gram reaction. The strain was able to grow at 0-1 % (w/v) NaCl, pH 5-10 and 20-35 °C, with optimal growth occurring at pH 7.0 and 28 °C without NaCl. Chemotaxonomic data revealed that strain WHSC-8T possesses ubiquinone Q-10 as the predominant respiratory quinone, C18 : 1ω7c, C16 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids, and sym-homospermidine as the major polyamine. Sphingomonadaceae-specific sphingoglycolipid was detected in the polar lipid patterns. The G+C content of the genomic DNA was 68.7 mol%. All of the above characters corroborated the assignment of the novel strain to the genus Sphingomonas. Strain WHSC-8T shared less than 97.0 % 16S rRNA gene sequence similarity with the type strains of other species of the genus Sphingomonas, except for Sphingomonas asaccharolytica DSM 10564T (97.5 %). The low DNA-DNA relatedness value and distinct phenotypic and chemotaxonomic characteristics distinguished strain WHSC-8T from closely related species of the genus Sphingomonas. Therefore, strain WHSC-8T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas hengshuiensis sp. nov. is proposed. The type strain is WHSC-8T ( = KCTC 42455T = CCTCC AB 2015265T).
