摘要： A method of producing hardwood pulp is provided. This method comprises treating hardwood chips with one or more than one Family 11 xylanase enzyme in the absence of adding an oxidizing enzyme for about 5 minutes to about 120 minutes, to produce a treated chip mixture. The treated chip mixture is then mechanically refined to produce the hardwood pulp.

摘要： A method for producing mechanical paper pulp comprises: impregnating unprocessed wood, whereby unprocessed wood is exposed to an impregnating composition comprising at least a laccase enzyme and a formula mediator (I), wherein R1 and R2 are identical or different groups, chosen from among a hydrogen atom, a hydrocarbon chain, linear or branched, saturated or unsaturated, comprising 1 to 14 carbon atoms, wherein each hydrocarbon chain can be replaced by one or more functional groups chosen from among —OH, —SO3, benzyl, amino, mercapto, keto or carboxyl, wherein R1 and R2 in combination can form a cyclical structure, to achieve impregnation of the wood; and mechanically refining the impregnated wood, such that a mechanical paper pulp is obtained. The disclosure also relates to an impregnating composition used in this method and to the use thereof in a method for producing mechanical paper pulp, as well as to a method for producing paper.
摘要翻译：一种用于生产机械纸浆的方法包括：浸渍未处理的木材，由此未处理的木材暴露于包含至少一种漆酶和式中介体（I）的浸渍组合物中，其中R1和R2是相同或不同的基团，选自氢原子，含有1至14个碳原子的直链或支链，饱和或不饱和的烃链，其中每个烃链可以被一个或多个选自-OH，-SO 3，苄基，氨基，巯基，酮或羧基，其中R1和R2组合可以形成循环结构，以实现木材的浸渍; 并对浸渍的木材进行机械精制，从而获得机械纸浆。本公开还涉及在该方法中使用的浸渍组合物及其在生产机械纸浆的方法中的用途以及生产纸的方法。
