Genome-based reclassification of as a later heterotypic synonym of , with the descriptions of subsp. subsp. nov. and subsp. subsp. nov. Free

Abstract

During the phylogenetic analysis of the genus , we found that an incorrect 16S rRNA gene sequence (accession number: D13727) was provided in the original description of NBRC 15098 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 DSM 24316. 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 that should be a later heterotypic synonym of. However, the distinctions in the genome size, hydrolysis of aesculin, -glucosidase and particularly the fatty acid profiles strongly support that strain DSM 24316 should be considered to represent a novel subspecies of Two novel subspecies are therefore proposed, namely subsp. subsp. nov. (type strain E-1-A=NBRC 15098=JCM 10195=DSM 8831=LMG 17326) and subsp. subsp. nov. (type strain UI2=DSM 24316=CCM 7428=MTCC 8591).
