中文摘要:

      生物酶具有高效、专一、反应温和、环保等特点，已广泛应用于食品、饲料、洗涤、纺织、造纸、制革、医药、石油等行业。其中，漆酶具有良好的去木素效果而被应用于制浆造纸流程的诸多环节。例如，将漆酶用在废纸脱墨、酶法漂白及助漂、胶黏物去除、纸张性能改善、废水处理等方面，可减少化学品用量，达到降低成本、减少环境污染的效果，其应用领域越来越广泛，具有较大的研究及应用价值。本文对漆酶在制浆造纸中的最新应用研究进展进行了综述，提升了漆酶未来的研究方向。

Abstract:

      Due to its high efficiency， specificity， mild and environmental friendly properties， enzymes have been widely used in food， feed， washing， textile， paper making， leather making， medicine， petroleum and other industries. As a kind of delignification enzyme， laccase is being applied to all aspects of pulping and papermaking processes because of its good effect of delignification. For example， laccase can be used in deinking， biobleaching， stickies removal and paper performance improvement. It has great research and application value because it can improve the physical properties of paper， reduce the dosage of chemicals， production cost and environmental pollution.
