Strain SW-150T grew optimally at 25–30 °C and in the presence of 2 % (w/v) NaCl. The isolate could be distinguished from other Sphingopyxis species in producing an orange pigment. It contained ubiquinone-10 as the predominant respiratory lipoquinone and C18 : 1 ω7c and C17 : 1 ω6c as the major fatty acids. No 3-hydroxy fatty acids were detected. Major polar lipids were sphingoglycolipid, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content was 63 mol%. Comparative 16S rRNA gene sequence analyses showed that strain SW-150T was phylogenetically affiliated to the genus Sphingopyxis of the family Sphingomonadaceae. Similarity values between the 16S rRNA gene sequences of strain SW-150T and the type strains of Sphingopyxis species ranged from 91·6 to 94·2 %, making it possible to categorize strain SW-150T as a species that is separate from previously described Sphingopyxis species. On the basis of phenotypic properties and phylogenetic distinctiveness, SW-150T (=KCTC 12231T=DSM 16222T) should be classified as the type strain of a novel Sphingopyxis species, for which the name Sphingopyxis baekryungensis sp. nov. is proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63495-0
