Abstract

Comparative analyses of SL-205 and NA10B were conducted for clarifying their taxonomic relationship. The sequences of the 16S rRNA gene and nine housekeeping genes of SL-205 and NA10B shared high similarities, above 98.8 %. Whole-genomic comparison between the two strains revealed a digital DNA–DNA hybridization estimate of 85.1 % and an average nucleotide identity of 98.3 % that were well above respective recognized thresholds for bacterial species delineation, strongly indicating that they represent the same genomospecies. The metabolic, physiological and chemotaxonomic features of SL-205 were also shown to be congruent with those of NA10B. Therefore, we conclude that Qiu . 2015 is a later heterotypic synonym of Khan and Hiraishi 2003.
