A polyphasic taxonomic characterization was performed on the novel isolate. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that strain SL-205T is a member of the genus Diaphorobacter. High levels of 16S rRNA gene sequence similarity were found between strain SL-205T and Diaphorobacter nitroreducens NA10BT (99.4 %) and Diaphorobacter oryzae RF3T (98.5 %), respectively. However, the DNA–DNA relatedness values between strain SL-205T and D. nitroreducens NA10BT and D. oryzae RF3T were 57 ± 1 % and 45 ± 1.5 %, respectively. The G+C content of the genomic DNA of strain SL-205T was 66.8 mol%. The major fatty acids consisted of summed feature 3 (including C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and C18 : 1ω7c. Ubiquinone Q-8 was the only respiratory quinone; the polar lipid profile comprised phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and one uncharacterized phospholipid. We conclude that strain SL-205T represents a novel species of the genus Diaphorobacter for which the name Diaphorobacter polyhydroxybutyrativorans is proposed; the type strain is SL-205T ( = ACCC 19739T = DSM 29460T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000353
