生物转化是指利用全细胞或提取酶作为催化剂将底物转化成目标产物的过程.与传统的化学合成方法相比,生物转化的方法可以在低污染、低能耗、高特异性的条件下进行,它可以替换多步化学反应成一步酶催化反应或是引入化合物结构的多样性,所以目前广泛应用于有机溶剂、聚合物材料、医药工业中间体、有机化学光学对映体、抗生素、维生素等重要工业产品的生产 Biotransformation refers to the process of converting a substrate into a target product using whole cells or extraction enzymes as a catalyst.Compared with the conventional chemical synthesis methods, bioconversion can be carried out under conditions of low pollution, low energy consumption and high specificity , It can replace the multi-step chemical reaction into one-step enzymatic reaction or the introduction of compound structure diversity, so it is widely used in organic solvents, polymer materials, pharmaceutical industry intermediates, organic optical enantiomers, antibiotics, vitamins, etc. Production of important industrial products
