摘　　要：本试验使用两种不同来源的混合菌群,经驯化后,设计L9(33)的正交摇瓶试验来考察温度、pH、菌群搭配三种因素对含钛铀矿石的浸出效果。采用双层平板技术初步分析与鉴定了初始菌与结束菌的种群变化情况;正交分析结果显示适应细菌浸出此类铀矿石的最佳条件是初始pH 2.0,37℃恒温,菌群组合为334。Using two kinds of mixed bacteria that by domestication in this test, the effect of bioleaching uranium ore in conditions with temperature, pH value and strains was explored by L433）orthogonal design. By using overlay technique to identify the changes of mixed bacteria from the beginning and the end. The result by orthogonal design showed that optimum condition for this uranium bioleaching were pH 2.0 in substrate, in constant temperature of 37 ℃, strain was 334.
