中文摘要：
酶作为一种生物催化剂，具有专一性强、催化效率高、在常温常压等温和条件下能进行操作等优点，从而引起众多学者的兴趣．传统酶学研究的是酶在水溶液中的催化行为，这使得人们产生了误解，认为只有在水溶液中酶才能保持活性，有机溶剂会使酶变性失活．1984年，美国麻省理工工学院的科学家Klibanov首次发现有许多酶可用于有机溶剂，从而解决了有机化合物在水介质中的低溶解性限制酶催化剂应用的问题，酶不仅能够在有机溶剂中保持稳定，而且还显示出很高的催化转酯活力．这一发现为酶学研究和应用带来了又一次革命性飞跃，从而促进了非水酶学的兴起，使之成为目前重要的酶技术之一．其中研究较多的是脂肪酶，脂肪酶不仅能催化油脂水解，而且在非水介质中也能催化油脂的酯交换反应，用来提高油脂的品位．随着研究的深入和学科的交叉，各种新的酶促反应体系也相继被发现，大大拓宽了酶催化反应的应用范围，使酶法合成逐步发展成为与化学法合成相互补充的合成方法．近年来非水介质中的不同反应体系的酶催化反应，主要有：有机溶剂体系、反相胶束体系、超临界体系、气相体系等，其中无溶剂体系中的酶促反应是非水体系中酶促反应的特例．
