DNA–DNA relatedness values between strain UI2T and Sphingopyxis terrae IFO 15098T and other related strains were found to be less than 46 %. The major cellular fatty acids of strain UI2T were C18 : 1 ω7c (28.3 %), C16 : 0 (14.4 %), 11-methyl C18 : 1 ω7c (10.9 %), C17 : 1 ω6c (9.6 %) and summed feature 3 (consisting of C16 : 1 ω7c and/or C15 : 0 iso 2-OH; 14.7 %). The DNA G+C content of strain UI2T was 68 mol%. On the basis of DNA–DNA hybridization, phenotypic characteristics and phylogenetic analysis, strain UI2T is found to represent a novel species of the genus Sphingopyxis, for which the name Sphingopyxis ummariensis sp. nov. is proposed. The type strain is UI2T (=CCM 7428T =MTCC 8591T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.008805-0
