摘要： Methods for reducing energy required for a pulp refining processes by treating a mechanical pulp with a hemicellulase composition are presented. The enzymatic treatment can be carried out at a temperature of from about 10° C. to about 90° C., and/or at a pH of from about 2 to about 10. Paper made from the treated pulp has improved strength over paper made from untreated pulp.

摘要： The invention relates to processes for treating a pulp, and for making a paper material such as paper, cardboard linerboard, corrugated paperboard, tissue, towels, corrugated containers boxes etc. these processes comprising an alkaline treatment of a pulp, a treatment with a pectin lyase and/or a pectate lyase, and, if desired, a draining of the pulp. Pectate lyase in combination with pectinesterase may be substituted for pectin lyase. The invention also relates to the use of xylanase, pectin lyase, pectate lyase, and/or the combination of pectate lyase with pectinesterase for anionic trash reduction and/or reduction of cationic demand of a paper pulp.

摘要： The invention relates to the use of certain lipolytic enzymes such as cutinases and lipases in the manufacture of paper and paper products from recycled paper. Examples of such enzymes are derived from strains of Humicola, Candida, Fusarium and Pseudomonas. By use of these enzymes, the problems relating to the so-called “stickies” derived from waste paper are reduced.
摘要翻译： 本发明涉及某些脂肪分解酶如角质酶和脂肪酶在再生纸制造纸和纸制品中的用途。 这些酶的实例源自腐质霉（Humicola），假丝酵母属（Candida），镰刀菌属（Fusarium）和假单胞菌属（Pseudomonas）的菌株。 通过使用这些酶，与废纸所得的所谓“粘性”相关的问题减少了。
