| 摘 要： | 从对虾养殖池塘中筛选出多株具有好氧反硝化性能的芽孢杆菌,其中芽孢杆菌YX-6能够在14 h内将ρ(亚硝酸盐氮)由10 mg/L降至0;ρ(DO)为5.2~5.8 mg/L时,该菌对亚硝酸盐氮的去除率接近100%.试验选取具有降氮功能的芽孢杆菌作为阳性对照菌,比较研究了芽孢杆菌YX-6在不同pH,温度,ρ(亚硝酸盐氮)和盐度时的好氧反硝化性能.结果表明,芽孢杆菌YX-6的好氧反硝化性能显著高于阳性对照菌(P0.05).通过对芽孢杆菌YX-6的形态学观察、生理生化及16S rDNA分子鉴定,初步鉴定其为凝结芽孢杆菌(Bacillus coagulans).

| Abstract: | Many Bacillus strains with aerobic denitrification character were isolated from the water and sediment of shrimp culture ponds.Among them,the Bacillus YX-6 could degrade nitrite nitrogen from 10(mg/L) to zero in 14 h,as well as approximately 100% of nitrite nitrogen removal rate at a DO mass concentration of 5.2-5.8(mg/L).Furthermore,in comparison with the denitrifying Bacillus selected as the positive control,the denitrification characteristics of Bacillus YX-6 were tested under different pH,temperature,ni... |
