摘要:本研究以3年青檀熟皮为研究对象，探究了单一漆酶、木聚糖酶及漆酶-木聚糖酶复合酶预处理对原料组分溶出、纤维及纸张性能的影响，同时评估了漆酶-木聚糖酶复合酶预处理在低碱制浆工艺中的应用潜力。结果表明，漆酶-木聚糖酶复合酶预处理具有显著的协同效应，与单一漆酶、木聚糖酶预处理相比，其木质素脱除率提升至36.7%，与不含酶的预处理相比，打浆效率提高了14.8%，并显著改善了制备纸张的抗张、耐破及撕裂指数。在用碱量降低30%的条件下，相比传统高碱制浆工艺，采用漆酶-木聚糖酶复合酶预处理，打浆效率提高6.8%，白度提高4.84个百分点，且制备纸张的物理强度仍优于传统高碱制浆工艺。
Abstract:This study investigated the effects of individual laccase and xylanase pretreatment， as well as laccase-xylanase composite enzyme pretreatment， on the dissolution of raw material components， fiber and paper properties with three-year-old mature Pteroceltis Tatarinowii bark as the subject. It also evaluated the application potential of laccase-xylanase composite enzyme pretreatment in low-alkali pulping processes. The results indicated that the laccase-xylanase composite enzyme pretreatment exhibited significant synergistic effects. Compared to individual laccase and xylanase pretreatments， it increased lignin removal to 36.7%， with refining efficiency improved by 14.8%， and significantly enhanced paper tensile， bursting， and tear index. Under conditions of 30% reduced alkali consumption， pulp beating efficiency increased by 6.8%， brightness improved by 4.84 percentage point， and paper physical strength remained superior to that produced by traditional high-alkali pulping process.
