摘　　要：以500mg/L的高浓度(NH_4)_2SO_4为唯一氮源的选择培养基,从市售的腐乳中分离筛选出1株对高氨氮含量中氨氮降解效率较高的菌株FR08,经形态学和生理特性初步鉴定其为巨大芽孢杆菌。实验结果表明:在初始氨氮质量浓度为500mg/L,初始pH值为7.0,培养温度为28℃时,该菌株48h对氨氮降解率为73.64%。该菌可应用于养殖废水、生活污水及氨氮污染较严重的土壤的氨氮处理。A high effective bacterium FR08 degrading ammonia nitrogen has been isolated from the fermented bean curd by the selected culture medium with （NH4）2SO4 as exclusive nitrogen source. The degrading rate of NH4＋-N by FR08 is over 73.64% with 48 h at initial concentration NH4＋-N of 500 mg/L, initial pH of aryabhattai primarily. It in sewage, urban sewage 7. 0, culture temperature of 28 ℃. FR08 strain is identified as Bacillus can be treated to control the serious problems of ammonia nitrogen pollution and soil.
