摘　　要：漆酶能够作用的底物非常广泛,包括木质纤维素等大分子聚合物,且在催化反应时可将该类物质还原成水和其他小分子物质,不会造成二次污染,因此,漆酶素有“绿色催化剂”之称,具有被广泛运用于工业生产中的广阔前景。对游离漆酶进行固定化处理能够使其进一步适应工业生产中的恶劣环境,提高稳定性、可循环利用率,扩大耐受pH和温度范围。真菌漆酶作为漆酶的重要来源,本文对其性质、生产,以及新型的固定化方法和各个领域的应用进行了概述。Laccases are so called as green catalysts since they can reduce a vast of substrates including lignocellulose and other macromolecular polymers into water and low-molecular weight by-products,without formation of secondary pollutants.Therefore,laccases have huge potentials in various industrial applications.For free laccases,immobilization treatment is capable of enhancing their capacities to adapt harsh conditions for industrial utilization,thermostability,reusability,and expanding the tolerant ranges of pH and temperature.As fungal laccases are important origins of laccases,their properties,production,current immobilization strategies,and potential applications in various fields were summarized in this review.
