摘　　要：从具有脱臭功能的曝气生物滤池中分离出一株能同时脱硫和氨氮的菌株TS-1。根据形态学、生理生化特征及16S rDNA基因序列分析结果,初步鉴定该菌株为巨大芽孢杆菌(Bacil-lus megaterium)。对菌株TS-1的生长性能和脱硫、脱氨氮性能进行了测试,结果表明,在(30±2)℃、转速为150r/min的条件下,该菌株的最佳生长pH值为7.0,对数生长期为12～32h;当S2-和NH4+-N分别为80、88mg/L时,对硫化物和氨氮的去除率分别可达91.8%、96.6%,且去除率随底物初始浓度的增加而逐渐降低。A strain TS-1 for desulfurization and ammonia nitrogen removal was separated from sludge in a BAF with deodorizing effect. Through morphological and physio-biochemical experiments and 16S rDNA genetical sequence analysis,this strain was identified as Bacillus megaterium. The growth,desulfurization and ammonia nitrogen removal characteristics of this strain were tested. The results show that under the conditions of (30±2) ℃ and rotating speed 150 r/min,the optimum pH for growth is 7.0,and the logarithmic gro...
