| 摘 要： | 从印染废水及污水处理厂污泥中分离得到7株聚乙烯醇(PVA)降解菌，经紫外线诱变，获得高活性变异菌株UV2．对UV2进行PVA降解试验，确定了其降解特性参数，并与出发菌株B自的降解性能相比较．研究表明，诱变菌株W2对模拟废水中PVA的降解速率及降解活性均明显高于出发菌株B白，且适应环境的能力更强．在最佳降解条件下，对PVA的降解率达93％以上，比出发菌株提高了30％．

| Abstract: | Isotation, culturing and degradation property were studied for polyvinyl alcohol degrading bacterium,which were isolaed from dyeprinting wastewater and activated sludge samples. All these bacterium are treated by ultraviolet ray ,and a bacterium labeled as UV_2 is obtained. Through the degradation test of UV_2 and the original strain,a series of parameters are determined. It is indicated that both degradation rate and activity of UV_2 to simulated wastewater which contain PVA are higher the original strain sharply.Under optimum circumstance,the removing ratio of PVA reaches at above93%,which is higher 30% than the original strain. |
