    • A process using a multicomponent enzyme preparation to treat chips that have been crushed using a device that combines shear and compressive forces where treatment occurs mainly during decompression and reduces the specific energy consumption and/or increasing production of subsequent refining while maintaining or increasing handsheet physical properties. The enzyme preparation is to have a major endoglucanase activity, a significant mannanase activity and a slight cellobiohydrolase activity. This enzyme mixture is prepared from a genetically modified strain of Trichoderma reseii.
    • 使用多组分酶制剂来处理已经使用结合剪切力和压缩力的装置破碎的碎片的方法,其中处理主要在减压期间发生,并且减少比能量消耗和/或增加后续精炼的产量,同时保持或增加手抄纸物理性质 。 该酶制剂具有主要的内切葡聚糖酶活性,显着的甘露聚糖酶活性和轻微的纤维二糖水解酶活性。 该酶混合物由遗传修饰的木霉菌株制备。
