摘要： A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterium, designated strain FJAT-25547(T), was isolated from the purplish paddy soil collected from Linshan Township, Yanting Prefecture of Sichuan Province in PR China (31 degrees 16'N 105 degrees 27'E). Growth was achieved aerobically at temperatures between 15 and 40 degrees C (optimum 30 degrees C), with between 0 and 10.0% NaCl (w/v) (optimum 4 %) and in the range of pH 5.0-12.0 (optimum pH 9.0). The cell-wall peptidoglycan contained meso-diaminopimelic acid, and the main isoprenoid quinone was MK-7. The major fatty acids were iso-C-15 : 0 (55.4 %), anteiso-C15:0 (22.2 %), iso-C-16:0 (5.1 %) and iso-C-14: 0 (6.5%). The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain FJAT-25547(T) was a member of the genus Bacillus and was most closely related to Bacillus horneckiae DSM 23495(T) (97.7% similarity), Bacillus eiseniae A1-2(T) (97.5 %), Bacillus mesophilum IITR-54(T) (97.2 %) and Bacillus kochii WCC 4582(T) (97.0 %). The average nucleotide identity value between strain FJAT-25547(T) and the type strain of the most closely related species, B. horneckiae DSM 23495(T), was 77.7 %, less than the proposed cut-off value of 96.0% for differentiating species within the genus. The in silico DNA-DNA hybridization value of strain FJAT-25547(T) with the most closely related species was 22.7 %, < 70 %, again indicating they belong to different taxa. The DNA G+C content of strain FJAT-25547(T) was 39.1 mol%. This taxono-genomics study revealed that strain FJAT-25547(T) represents a novel species of the genus Bacillus for which the name Bacillus praedii sp. nov. (type strain FJAT-25547(T) = CCTCC AB 2015208(T) = DSM 101002(T)) is proposed.
