摘要： Strain SJQ9(T), an aerobic bacterium isolated from a soil sample collected in Shanghai, PR China, was characterized using a polyphasic approach. It grew optimally at pH 7.0, 30-35 degrees C and in the presence of 1 % (w/v) NaCl. A comparative analysis of 16S rRNA gene sequences showed that strain SJQ9(T) fell within the genus Aquabacterium. The closest phylogenetic relatives of strain SJQ9(T) were Aquabacterium citratiphilum DSM 11900(T) (98.6 % sequence similarity) and Aquabacterium commune DSM 11901(T) (96.4 %). Cells of the strain were Gram- stain-negative, motile, non-spore-forming, rod-shaped and positive for oxidase activity and negative for catalase. The chemotaxonomic properties of strain SJQ9(T) were consistent with those of the genus Aquabacterium: the major fatty acid was summed feature 3 (C-16:1 omega 6c and/or C-16:1 omega 7c). The isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content was 65.7 mol%. Strain SH9(T) exhibited a DNA-DNA relatedness level of 34 +/- 2 % with A. citratiphilum DSM 11900(T) and 28 +/- 3 % with A. commune DSM 11901(T). Based on the obtained data, strain SJQ9(T) represents a novel species of the genus Aquabacterium, for which the name Aquabacterium soli sp. nov. is proposed. The type strain is SJQ9(T) (=JCM 33106(T)=CCTCC AB 2018284(T)).
