Abstract
The present invention is in the field of paper production, more in particular it relates to the process of wood pulping. It provides useful biological methods and compounds for reducing the energy requirements of the production of wood pulp. It describes a method for reducing the energy requirement of a thermo-mechanical pulping (TMP) process wherein cellulose fibers are recovered from a biomass comprising lignocellulosic material, wherein the lignocellulosic material is treated with a CotA laccase before recovering the cellulose from the lignocellulosic material.
