Cells of the strain were Gram-negative, strictly aerobic, non-motile rods and the strain formed yellow-pigmented colonies on 100-fold-diluted nutrient broth. Strain SY-6T grew at pH 6.0–7.0 (optimal growth at pH 7.0), at 10–37 °C (optimal growth at 28 °C) and at salinities of 0–0.5 % (w/v) NaCl, growing optimally at 0.01 % (w/v) NaCl. On the basis of 16S rRNA gene sequence analysis, strain SY-6T was shown to belong to the genus Sphingomonas and showed the closest phylogenetic similarity to Sphingomonas polyaromaticivorans B2-7T (96.7 %). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. The predominant ubiquinone and polyamine were Q-10 and sym-homospermidine, respectively. The major fatty acids were C18 : 1ω7c and C16 : 0. The DNA G+C content of the novel isolate was 65.3 mol%. On the basis of the evidence from this polyphasic study, strain SY-6T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas oligoaromativorans sp. nov. is proposed. The type strain is SY-6T ( = KACC 12948T = NBRC 105508T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.052894-0
