固定化漆酶降解水中酚类污染物研究进展

Research Progress on Degradation of Phenolic Pollutants by Immobilized Laccase in Water

酚类化合物污染行为与有效控制一直是污水处理领域研究热点之一.漆酶作为一种氧化还原酶,对水中酚类污染物具有良好的去除效果,但游离态漆酶处理水中酚类污染物存在稳定性差、活性损失快、难以重复使用等问题,也是漆酶在污水处理领域应用的瓶颈问题.因此,对游离态漆酶进行固定化处理,已成为漆酶研究领域的热点之一.本文综述了漆酶固定化的方法、载体以及固定化漆酶对水中酚类污染物的去除机制和影响因素,并对固定化漆酶研究进行了展望.

Phenolic compounds pollution behavior and effective control has been one of the research focuses in the field of wastewater treatment.As an oxidoreductase,laccase has a good removal effect on phenolic pollutants in water.However,the free laccase has some problems in the treatment of phenolic pollutants,such as poor stability,rapid loss of activity,and being difficult to reuse.It is also a bottleneck problem in the application of laccase in sewage treatment.Therefore,the immobilization of free laccase has become one of the hotspots in laccase research.In this paper,the methods and carriers of laccase immobilization,as well as the removal mechanism and factors of phenolic pollutants in water by immobilized laccase are reviewed,and the research of immobilized laccase is prospected.
