RT Journal Article SR Electronic(1) A1 Liu, Yang A1 Zhu, Hong-HuiYR 2019 T1 Diaphorobacter polyhydroxybutyrativorans Qiu et al. 2015 is a later heterotypic synonym of Diaphorobacter nitroreducens Khan and Hiraishi 2003 JF International Journal of Systematic and Evolutionary Microbiology, VO 69 IS 9 SP 2954 OP 2957 DO https://doi.org/10.1099/ijsem.0.003582 PB Microbiology Society, SN 1466-5034, AB Comparative analyses of Diaphorobacter polyhydroxybutyrativorans SL-205T and Diaphorobacter nitroreducens NA10BT were conducted for clarifying their taxonomic relationship. The sequences of the 16S rRNA gene and nine housekeeping genes of SL-205T and NA10BT 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-205T were also shown to be congruent with those of NA10BT. Therefore, we conclude that Diaphorobacter polyhydroxybutyrativorans Qiu et al. 2015 is a later heterotypic synonym of Diaphorobacter nitroreducens Khan and Hiraishi 2003., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003582
