摘  要:
从甲鱼池底淤泥中筛选的细菌,对其脱氮特性进行研究。实验以芽孢杆菌JY14为研究对象,通过单因子实验测定不同因素对其亚硝酸氮去除的影响。实验表明:菌株JY14在亚硝酸氮浓度为3 mg/l时,1%(v/v)左右的接种量,经30℃、16 h,150 r/min震荡培养,亚硝酸氮去除率可达99.50%。此菌株具有较好的实验室降低亚硝酸氮效果,在去除亚硝酸氮方面有良好的市场前景。

摘  要:
A bacteria was isolated from the sludge at the bottom of turtle culture poud, and its nitritenitrogen removing characteristics was studied. To measured JY14 characterization of nitrite-nitrogen removing in a single-factor experiment. Results showed the 99.50 percent of nitrite nitrogen removing under the following conditions:the inoculation age of 16 hours, the initiation concentration of sodium nitrite of 3 mg/l, the inoculation quantity of 1%, temperature as 30 ℃,rotation speed of the shaker being 150 r/min. This strain was better in nitrite nitrogen removing in the lab and had great development potential application prospects in the production.
