摘要： A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterium, designated FJAT-27215(T), was isolated from grass soil collected from Wudalianchi in the Heilongjiang Province of China. Growth was observed at 10-60 degrees C (optimum 30 degrees C), in 0 and 3.0% NaCl (optimum 0 %) and at pH 5.0-10.0 (optimum 7.0), respectively. The cell-wall peptidoglycan contained meso-diaminopimelic acid and the isoprenoid quinone was MK7. The main fatty acids were iso-C-15:0, anteiso-C-15:0, anteiso-C-17:0, and iso-C-16:0. The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidyl ethanolamine. Phylogenetic analysis based on 16S rRNA gene sequences affiliated strain FJAT-27215(T) to the genus Bacillus. Strain FJAT-27215(T) showed high sequence similarities to Bacillus encimensis SGD-V-25(T) (98.6 %), Bacillus badius NBRC 15713(T) (98.6 %), Domibacillus indicus SD111(T) (96.9 %) and Bacillus thermotolerans SgZ-8(T) (96.5 %). The average nucleotide identity values between strain FJAT-27215(T) and the type strains of closely related species were much lower than the 96% threshold value for delineation of genomic prokaryotic species. The in silico DNA-DNA hybridization values between strain FJAT-27215(T) and the most closely related strain B. encimensis SGD-V-25(T) showed a similarity of 22.4% and lower than 70 %, indicating that they belong to different taxa. The phenotypic characters and taxono-genomics study revealed that strain FJAT-27215(T) represents a novel Bacillus species, for which the name Bacillus wudalianchiensis sp. nov. is proposed. The type strain is FJAT-27215(T) (= CCTCC AB 2015266(T) = DSM 100757(T)).
