Abstract

In the present study, the taxonomic position of YSP-3 was evaluated using phylogenetic and genome-based comparison. YSP-3 showed the highest 16S rRNA gene sequence similarity to M30 (98.4 %), followed by K1-5 (97.5 %) and FJAT-45347 (97.2 %). In phylogenetic (based on 16S rRNA gene sequences) and phylogenomic (based on 71 bacterial single-copy genes) trees, YSP-3 clustered with the members of the genus . The amino acid identity (AAI) values between YSP-3 and the members of the genus were >65 %, which is above the cut-off level (65–95 %) for genus delineation. The average nucleotide identity (ANI) values between YSP-3 and the members of the genus were <95 %, which is lower than the threshold value (95–96 %) for bacterial species delineation. The AAI value suggested that YSP-3 was a member of the genus while the ANIb value suggested it as a novel species of the genus . Based on the results, we propose to transfer to the genus as comb. nov.
