Abstract: 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.

Abstract: A process using a multicomponent enzyme preparation to treat screened once refined pulps and reduces the specific energy consumption and/or increasing production while maintaining or increasing handsheet physical properties. The enzyme preparation has a major endoglucanase activity, a significant mannanase activity and a relatively small cellobiohydrolase activity. This enzyme mixture is prepared from a genetically modified strain of Trichoderma reseii.
