| Abstract |
During the phylogenetic analysis of the genus Sphingopyxis, we found that an incorrect 16S rRNA gene sequence (accession number: D13727) was provided in the original description of Sphingopyxisterrae NBRC 15098T and the wrong sequence has been adopted and used for a long time. It should be replaced by the new correct 16S rRNA gene sequence (accession number: MF618306). The new sequence shared the highest similarity (99.8 %) with that of Sphingopyxisummariensis DSM 24316T. The average nucleotide identity (ANI) (96.87 %) and digital DNA-DNA hybridization (75.30 %) values based on the whole-genome sequences and almost the same phenotypic and chemotaxonomic characteristics of the two type strains revealed thatSphingopyxisummariensis should be a later heterotypic synonym ofSphingopyxisterrae. However, the distinctions in the genome size, hydrolysis of aesculin, α-glucosidase and particularly the fatty acid profiles strongly support that strain DSM 24316T should be considered to represent a novel subspecies ofSphingopyxisterrae. Two novel subspecies are therefore proposed, namely Sphingopyxisterraesubsp. terrae subsp. nov. (type strain E-1-AT=NBRC 15098T=JCM 10195T=DSM 8831T=LMG 17326T) and Sphingopyxisterraesubsp. ummariensis subsp. nov. (type strain UI2T=DSM 24316T=CCM 7428T=MTCC 8591T).
