  • METHOD FOR SAVING ENERGY IN PAPER PRODUCTION
    Publication number: 20190003120
    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.

  • Method for improving the fermentable sugar yield from lignocellulosic
    Patent number: 9840726
    Abstract: The invention relates to processes for the conversion of biomass into carbohydrates, notable fermentable sugars. It provides means and methods for increasing the yield of enzymatic digestion of a biomass, in particular in those cases where cellulose is converted into sugars using a cellulose converting enzyme. More in particular, the invention relates to a method for producing a fermentable sugar from a lignocellulosic material wherein the lignocellulosic material is contacted with a laccase and an enzyme capable of degrading cellulose, either simultaneously or in a sequentially deferred fashion, wherein the laccase is the Bacillus spore coat protein CotA.
