Beschreibung
Zusammenfassung:	A process for the manufacture of a lignocellulose-based product from a lignocellulosic material comprises treating the lignocellulosic material and a phenolic polysaccharide with an enzyme capable of catalyzing the oxidation of phenolic groups, in the presence of an oxidizing agent. Suitable phenolic polysaccharides include phenolic starches or phenolic cationic starches derived from starches obtained from sources such as potato, corn, waxy corn, wheat, rice, sorghum, waxy sorghum, sago, arrowroot or tapioca. Cette invention concerne un procédé de fabrication, à partir d'une matière lignocellulosique, d'un produit à base de lignocellulose. Ledit procédé consiste à traiter la matière lignocellulosique et un polysaccharide phénolique avec un enzyme capable de catalyser l'oxydation de groupes phénoliques, en présence d'un agent oxydant. Les polysaccharides phénoliques convenant à ce procédé comprennent les amidons phénoliques et les amidons phénoliques cationiques dérivés des amidons provenant de sources telles que la pomme de terre, le maïs, le maïs cireux, le blé, le riz, le sorgho, le sorgho cireux, le potamot pectiné, l'arrow-root ou le tapioca.
