A Gram-stain-negative, strictly aerobic, motile, yellow, rod-shaped bacterium, designated ZDH117T, was isolated from soilsampled atthe Danxialandformin Guangdong Province, PR China. The 16S rRNA gene sequence of strain ZDH117T had highest similarityvalues to Sphingomonas adhaesiva DSM 7418T (97.5 %), Sphingomonas desiccabilis CP1DT (97.3 %) and Sphingomonas ginsenosidimutans KACC 14949T (97.2 %). However, phylogenetic analyses based on 16S rRNA gene sequences demonstrated that strain ZDH117T clustered with Sphingomonas zeicaulis 541T (96.17 %) and Sphingomonas sanxanigenens DSM 19645T (95.95 %). The genomic average nucleotide identity values of ZDH117T with S. adhaesiva DSM 7418T, S. desiccabilis CP1DTand S. ginsenosidimutans KACC TT were 75.1, 75.2 and 75.0 %, respectively. The G+C content of the genomic DNA was 67.6 mol%. Strain ZDH117T was characterized to have ubiquinone-10 as the predominant respiratory quinone, sym-homospermidine as the major polyamine and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c), C14 : 0-2OH, C16 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) as the major cellular fatty acids (>5 % of total). The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid, an unidentified phospholipid and three unidentified lipids. On the basis of its phenotypic, chemotaxonomic and phylogenetic characteristics, strain ZDH117T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas gilva sp. nov. is proposed. The type strain is ZDH117T (=KCTC 62894T=CCTCCAB 2018262T).
