摘要
研究了不同盐度、pH和温度条件下荚膜红假单胞菌Rhodopseudomonas capsulata C12、枯草芽孢杆菌Bacillus subtilis及假丝酵母菌Candida sp．对高浓度总氨氮（9～10mg／L）和亚硝酸盐氮（1～2mg／L）净化作用的影响。结果表明：荚膜红假单胞菌C12可在盐度为0～40、pH为7～9、温度为25—37℃条件下的淡水、海水养殖中发挥高效净化亚硝酸盐氮的作用；枯草芽孢杆菌较适宜在盐度为0～20、pH为5．5-8．5、温度为20-57℃条件下的水体中发挥净化总氨氮的作用；而假丝酵母菌净化总氨氮的较适宜条件为淡水、pH5．5～7．0、温度20～30℃。
The effects of different salinity, pH, and temperature on purification of NH3 - N（9 - 10 mg/L） and NO2 -N（ 1 -2 mg/L） by the C12（Rhodopseudomonas capsulata）,Bacillus subtilis and Candida sp. were studied. The C12 was found to have good purification of the water in aquaculture at salinity of 0 -40, pH 7 -9, and water temperature of 25 -37 ℃. The suitable conditions for Bacillus subtilis to eliminate NH3 -N were as the following： a salinity of 0 - 20, pH 5.5 - 8.5, and 20 - 37 ℃ and the good purification by Candida sp. was observed in the freshwater with pH 5.5 - 7.0, and 20 - 30 ℃.
