Abstract A Gram staining-negative, yellow-colored, rod-shaped, non-motile and aerobic, designated strain 17J27-24T was isolated from a soil sample in Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 17J27-24T was related to the members of the family Sphingomonadaceae and formed a distinct monophyletic cluster within the genus Sphingomonas with Sphingomonas deserti (98.3% 16S rRNA gene sequence similarity). Growth was observed at 30 °C (optimum), at pH 7.0 (optimum), and in the absence of NaCl (%). The predominant cellular fatty acids were summed feature 8 (18:1 ω7c and/or 18:1 ω6c) and C17:1 ω6c. The major respiratory quinone was Q10. The polar lipids profile comprised of diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), and sphingoglycolipid (SGL). The DNA G + C content was 77.8 mol%. The average nucleotide identity (ANI) and digital DNA–DNA hybridisation (dDDH) values between 17J27-24T and its phylogenetically closest Sphingomonas deserti (KCTC 6 2411T) were below the established cut-off
