Abstract
L'invention concerne un procédé de fabrication d'un produit à base de lignocellulose. Ce procédé comprend les étapes consistant à mélanger dans un milieu de réaction (i) un polymère phénolique étant substitué par un groupe hydroxy phénolique; (ii) une lignocellulose présentant immobilisé, par rapport à une fraction cellulosique, un polypeptide hybride, ce polymère comprenant une enzyme capable de catalyser l'oxydation des groupes phénoliques ainsi qu'un peptide liant la cellulose; et (iii) un agent d'oxydation. L'invention concerne également une composition à utiliser dans le procédé et un produit à base de lignocellulose qui peut être obtenu au moyen de ce procédé.
