Laccase has the enormous potential to be implemented as the multitasking biocatalyst in whole process of paper making. The enzyme can utilize effectively for pulping, delignification of pulps as alone or in the combination with other bleaching enzymes. Laccase has been evaluated for the biografting of pulp fibers, decolorize and stabilize the effluent of the paper mills, biotransformation of high molecular weight (HMW) lignins to lower molecular weight (LMW) aromatic compounds. Further this enzyme has the huge possibilities to apply for deinking of old newsprint (ONP) and pitch removal from varieties of the different pulps. There is no doubt on versatility mode of action of laccases in paper industry, but still there is limited commercialization of this enzyme has been possible, because of laccases has the less redox potential (E0) and needs mediators for the oxidation of non phenolic substrates, production of enzyme is cost intensive at large scale. This review is providing the proper updated information on the state of the art of different applications of laccase in paper industry. It also confer the interpretation to the readers about the areas of extensively studied and the field where there is still much left to be done.
漆酶具有作为多功能生物催化剂在造纸全过程中应用的巨大潜力。该酶可单独或与其他漂白酶一起有效用于制浆、纸浆脱木素。已对漆酶进行了纸浆纤维的生物接枝、废水脱色和稳定、高分子量（HMW）木质素转化为低分子量（LMW）芳香族化合物的评估。此外，该酶在旧新闻纸（ONP）脱墨和各种不同纸浆中去除树脂方面具有巨大的应用潜力。漆酶在造纸工业中的多功能作用模式毋庸置疑，但由于漆酶的氧化还原电位（E0）较低，并且需要介体来氧化非酚类底物，因此该酶的大规模商业化仍然受到限制。这篇综述提供了关于漆酶在造纸工业中不同应用的最新信息。它还向读者解释了广泛研究的领域和仍有许多工作要做的领域。
