A novel Gram-staining-negative, non-motile and rod-shaped bacterial strain ZQBW(T), which was isolated from a diuron-polluted soil collected near Nanjing, PR China, was investigated for its taxonomic position by a polyphasic approach. ZQBW(T) grew well at pH 6.0-12.0 (optimum, pH 7.0), 26-35 C-degrees (optimum, 30 (degrees) C) and up to 0.5 % NaCl (optimally the absence of NaCl) in R2A broth. The major fatty acids of ZQBW(T) were C-18:1 omega(82.7 %) and C-18:0 (5.3 %). The polar lipid profile included the major compounds phophatidylcholine, phosphatidylglycerol and phosphatidylmethylethanolamine. The only respiratory quinone was ubiquinone Q-10. The G+Ccontent of genomic DNA was 67.0 mol%. Comparisons with 16S rRNA gene sequences revealed that ZQBW(T) has the highest sequence similarities with members of the genus Tabrizicola (<= 95.97 %), followed by Rhodobacter (<= 95.96 %) and Falsirhodobacter (95.95 %) which all belong to the family Rhodobacteraceae in the phylum Proteobacteria. Photosynthesis genes pufLM were not found and photosynthesis pigments were not formed in ZQBW(T). On the basis of the results from chemotaxonomic, phenotypic and phylogenetic analysis, ZQBW(T) represents a novel species of a novel genus, for which the name Xinfangfangia soli gen. nov., sp. nov. is proposed. The type strain is ZQBW(T) (=KCTC 62102(T)=CCTCC AB 2017177(T)).
