| 摘 要： | 通过正交试验考察了温度、pH值、初始Fe2+浓度及初始Fe3+浓度这4个因素以及这4个因子之间相互作用对氧化亚铁硫杆菌(即T.f菌)的生长速度的影响。建立了正交实验表L27(313),进行了27组实验,然后利用方差分析方法分析试验数据,判定温度和pH值相互作用对T.f菌生长情况影响显著。研究结果表明其最优适宜环境为:pH=2、温度28℃、初始Fe2+浓度0.15mol/L、初始Fe3+浓度为0.06mol/L。

| Abstract: | The effects of pH value, temperature, the initial concentrations of Fe2+ and Fe3+ as well as the interaction between these factors on the growth of thiobacillus ferrooxidans were investigated by orthogonal tests. An L27(313) orthogonal array was set up to carry out 27 groups of experiments, and the variance method was used to analyze the experimental data. The results showed that the interaction between temperature and pH value had a significant effect on the growth of thiobacillus ferrooxidans. The optimal environmental conditions of thiobacillus ferrooxidans growth were pH value of 2, temperature of 30℃, Fe2+ initial concentration of 0.15mol/L, and Fe3+ initial concentration of 0.06mol / L. |
