摘　　要：介绍白水循环系统中DCS的来源及危害,从DCS来源的角度阐述生物酶在控制白水循环系统中DCS的研究进展,并分别介绍了脂肪酶、果胶酶、漆酶的作用机理;最后对近年来果胶酶和脂肪酶的固化方法进行概述,为固定化方法的进一步发展提供了研究基础,并对固定化酶应用于造纸工业中的前景予以展望。In this paper the source of DCS and its harm to papermaking were illustrated, the application of enzyme in the white water recy- cling system was reviewed, and the mechanism of the effects of lipase, pectinase and laccase was also introduced. Finally, the methods of immobilizing lipase and pectinase were introduced, and the prospect of application of the immobilized enzyme in papermaking industry was discussed.
