摘要： Two Gram-stain negative, coccoid to oval-shaped, non-spore-forming bacteria (LR4(T) and LR4-1), isolated from the soil of a pesticide factory in Nanjing, China, were investigated for their taxonomic allocation by using a polyphasic approach. Both strains grew optimally at pH 7.0, 30 degrees C and in the absence of NaCl. Both strains were positive for catalase and oxidase activities. Q-10 was the predominant respiratory ubiquinone. The major polar lipids were phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and two unknown aminolipids. The major fatty acids (>10 % of the total fatty acids) were C-18:1 omega 7c/C(18:1 omega)6c (summed feature 8) and C-17:1 iso I/C-17:1 anteiso B (summed feature 4). Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the two isolates formed a distinct line within a Glade containing the genera Chelatococcus, Bosea, Camelimonas, Salinarimonas, Psychroglaciecola, Microvirga, Methylobacterium, Albibacter, Hansschlegelia and Methylopila in the order Rhizobiales, with the highest 16S rRNA gene sequence similarity to Chelatococcus asaccharovorans TE2(T) (94.12 %), followed by Bosea thiooxidans DSM 9653(T) (93.25 %). strains LR4(T) and LR4-1 were closely related on the basis of DNA DNA reassociation and therefore represent a single novel species. Based on phenotypic, chemotaxonomic and phylogenetic data, strains LR4(T) and LR4-1 represent a novel species of a new genus in the order Rhizobiales, for which the name Qingshengfania soli gen. nov., sp. nov. is proposed. The type strain of the type species is LR4(T) (=CCTCC AB 2015036(T)=KCTC 42463(T)).
