Enzyme-catalyzed synthesis is highly efficient and specific, making it widely used. This paper aims to study the method of molecular modification and fractionation of the Alcaligenes faecalis lipase to prepare L-menthol under optimal conditions.In this study, molecular biology and biochemical techniques will be used to modify the Alcaligenes faecalis lipase gene to improve its catalytic efficiency. In addition, enzyme engineering techniques will be used to fractionate the enzyme into different subunits. These subunits can then be reassembled to obtain an enzyme with high efficiency and specificity.In the process of preparing L-menthol, the optimal reaction conditions will be determined by design experiments. The ultimate goal of this study is to develop a highly efficient and specific enzyme-catalyzed synthesis method for L-menthol.精品文档---下载后可任意编辑【Keywords】Alcaligenes faecalis lipase, molecular modification, fractionation, L-menthol, enzyme engineering, design experiment
