Abstract

A comparative taxonomic study of and species was carried out using a phylogenomic approach based on comparison of the core genome, orthologous average nucleotide identity (OrthoANIu), Genome-to-Genome Distance Calculator (GGDC) and average amino acid identity (AAI). Phylogenomic analysis based on 976 core translated gene sequences obtained from their genomes showed that SP30, UAH-SP71, SSL50, M19-40 and DSM 21056 formed a robust cluster, clearly separated from the remaining species of closely related taxa. AAI between DSM 21056 and the species of the genus was ≥73.1 %, confirming that all these species belong to the same single genus. On the other hand, SSL50 and SP30 showed percentages of OrthoANIu and digital DNA–DNA hybridization of 98.4 % and 85.3 %, respectively, while these values among those strains and the type strains of the other species of and DSM 21056 were ≤80.8 and 67.8 %, respectively. Overall, these data show that SSL50 and SP30 constitute a single species and thus that SP30 should be considered as a later, heterotypic synonym of SSL50 based on the rules for priority of names. We propose an emended description of , including the features of . We also propose the reclassification of as comb. nov.
