摘要: A rod-shaped, endospore-forming, aerobic bacterium, designated FJAT-46582(T), was isolated from a sediment sample of the coastal region in Xiapu County, Fujian Province in China. Growth was observed at 10-30 degrees C (optimum, 25 degrees C), in 0-7.0 % NaCl (0 %) and at pH 6.0-11.0 (pH 8.0), respectively. The cell-wall peptidoglycan contained meso-diaminopimelic acid and the isoprenoid quinone was MK-7. The main fatty acids were anteiso-C-17:0 (26.5 %), anteiso-C-15:0 (19.6%), iso-C-15:0 (14.4%) and C-16:0 (10.5%). The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidyl ethanolamine. Phylogenetic analysis based on 16S rRNA gene sequences affiliated strain FJAT-46582(T) with the genus Bacillus, and showed the highest sequence similarity to Bacillus thermotolerans SGZ-8(T) (97.6 %) and Bacillus ectoinformans (97.1%). The average nucleotide identity and in silico DNA-DNA hybridization values between strain FJAT-46582(T) and the most closely related species were 72.3 and 22.9 %, respectively, which were much lower than the thresholds commonly used to define species (96 and 70 %, respectively) indicating that it belonged to a different taxon. The DNA G+C content was 44.2 mol%. The phenotypic characters and taxono-genomics study revealed that strain FJAT-46582(T) represents a novel Bacillus species, for which the name Bacillus xiapuensis sp. nov. is proposed. The type strain is FJAT-46582(T) (=JCM 33155=CCTCC AB 2017047(T)).
