Growth occurred at 10–41 °C and at pH 5.0–7.0, with optimum growth at 30 °C and pH 7.0. Additionally, growth occurred in conditions of 0–5 % (w/v) salinity, but not above 7 % NaCl. The 16S rRNA gene sequences of the novel strains shared the highest similarity with Sinorhodobacter ferrireducens SgZ-3T (97.1 %). The average nucleotide identity values between the novel strains and two type strains (S.inorhodobacter ferrireducens CCTCC AB2012026T and ‘ S inorhodobacter hungdaonensis’ CGMCC 1.12963T) were 78.4–78.9 %, which were lower than the proposed species boundary cut-off (95–96 %). The main polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified lipid and phosphatidylcholine. The main respiratory quinone was Q-10, and major fatty acids were C18 : 1ω7c and/or C18 : 1 ω6c. Based on data from a polyphasic taxonomy study, the novel strains represent a novel species of the genus Sinorhodobacter , for which the name Sinorhodobacter populi sp. nov. is proposed. The type strain is sk2b1T (=CFCC 14580T=KCTC 52802T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003300
