Abstract: The present disclosure relates to the field of papermaking, especially to the manufacture of paper with improved moisture- and water-resistance. The present disclosure also relates to a paper with improved moisture- and water-resistance obtained by the process as well as compositions useful in the process of making moisture- and water-resistant paper.

Abstract: The invention relates to obtaining lignin preparations of desirable molecular size and properties. It describes a method of de-polymerizing lignin of high molecular weight into low molecular weight lignin. More in particular, the invention provides a method for producing lignin with a low molecular weight wherein high molecular weight lignin is contacted with an alkaline laccase at alkaline pH in a reaction vessel and wherein the lignin with a molecular weight below 2 kDa is selectively removed from the reaction vessel during the reaction.

Abstract: The invention is in the field of enzymology. More in particular, it provides a method for the isomerization of glucose into fructose wherein the glucose is derived from lignocellulosic material. More in particular, it provides a method for converting glucose into fructose comprising the steps of: providing a composition comprising water, glucose and lignin, enzymatically converting the glucose to fructose in the presence of a glucose isomerase, and optionally purifying the fructose from the solution, wherein the glucose isomerase comprises an amino acid sequence that is at least 90% identical with the sequence according to SEQ ID NO: 1 or SEQ ID NO: 2.

Abstract: The invention relates to processes for the conversion of biomass into carbohydrates, notably reducing sugars. It provides means and methods for increasing the yield of enzymatic digestion of a biomass, in particular in methods wherein cellulose is converted into sugars using a cellulose-converting enzyme. More in particular, the invention provides a method for producing a reducing sugar from a lignocellulosic material, wherein the lignocellulosic material is contacted with a pectate lyase at a pH between 9 and 12, wherein the pectate lyase comprises an amino acid sequence according to SEQ ID NO: 1 or an amino acid sequence at least 70% identical with SEQ ID NO: 1.

Abstract: The invention is in the field of enzymology. More in particular, it provides a method for the isomerization of xylose into xylulose wherein the xylose is derived from lignocellulosic material.
