漆酶是一种含铜的多酚氧化酶,在介体分子作用下可进一步催化非酚类物质,且唯一的副产物是水,因其催化过程对环境污染小而受到青睐。综述了漆酶的结构与组成、漆酶及其介体体系催化机理、漆酶及其介体体系催化纤维机理及其在纤维改性中的应用,并对目前漆酶及其介体体系活化纤维的研究现状和发展趋势进行了评述。 Laccase is a copper-containing polyphenol oxidase that catalyses the non-phenolic substances under the action of mediator molecules and the only byproduct is water, which is favored for its low environmental pollution due to its catalytic process. The structure and composition of laccase, the catalytic mechanism of laccase and its mediator system, the catalytic fiber mechanism of laccase and its mediator system and its application in fiber modification are reviewed. At the same time, laccase and its mediator system are activated Fiber research status and development trend were reviewed.
