果胶酶及其在制浆造纸上的应用

Pectinase and Its Applications in Pulp and Paper Industry

综述了果胶酶在制浆造纸上应用的研究进展,从果胶酶系的分类和脱胶机理的角度出发,介绍了果胶酶及其相关微生物在韧皮纤维原料酶法和发酵浸渍法制浆中的作用条件和作用效果,着重介绍了果胶酶在湿部化学上降低阳离子需求量的作用,同时讨论了外界因子对其提高细小纤维和填料留着率效果的影响,并指出果胶酶对纸浆物理性能的影响。

The application of pectinase in pulp and paper industry are reviewed in this paper. According to the classification of pectinase and its action mechanism, the process conditions and effect of pectinase on bio-pulping of bast fiber material are introduce. Pectinase reduces the cationic demand in wet end chemistry is emphasized, the influence of external factors on the improvement of the retention of fines and fillers is also discussed, furthermore, the influence of pectinase on pulp physical properties is illustrated.
