title: Sphingomonas faucium sp. nov., isolated from canyon soil.
abstract: A Gram-stain-negative, strictly aerobic, non-motile, yellow, rod-shaped bacterium, designated strain E62-3T, was isolated from soil of Enshi Grand Canyon, Hubei province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain E62-3T was most closely related to Sphingomonas laterariae LNB2T. Strain E62-3T exhibited the highest 16S rRNA gene sequence similarity to Sphingosinicella vermicomposti YC7378T (96.0 %), Sphingobium xanthum NL9T (95.8 %), Sphingobium boeckii 469T (95.7 %) and Sphingomonas laterariae LNB2T (95.5 %) within the family Sphingomonadaceae. The major fatty acids (>5 %) of strain E62-3T were C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and C14 : 0 2-OH. The predominant respiratory quinone and polyamine were ubiquinone Q-10 and homospermidine, respectively. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The genomic DNA G+C content was 66.4 mol%. The genotypic, chemotaxonomic and phenotypic data revealed that the isolate represents a novel species of the genus Sphingomonas, for which the name Sphingomonas faucium sp. nov. is proposed. The type strain is E62-3T (=KCTC 42834T=CCTCC AB 2015300T).
