Beschreibung
Zusammenfassung:	In a first aspect, the present invention relates to an isolated aqueous enzymatic preparation obtained from the reaction of at least one oxidoreductase enzyme, preferably a laccase, and at least one natural or synthetic product, preferably a natural compound, said natural or synthetic product comprising, in the structure thereof, at least one phenol or alcohol group, which optionally has one or more hydrophobic chains, or at least one sterol group. In a second aspect, the present invention relates to the use of said isolated aqueous enzymatic preparation in the functionalization of the surface of paper or cellulosic substrates. Preparación enzimática acuosa aislada y uso para la funcionalización de la superficie del papel o soportes celulósicos.En un primer aspecto, la presente invención se refiere a una preparación enzimática acuosa aislada obtenida a partir de la reacción de por lo menos una enzima oxidorreductasa, preferiblemente una lacasa, y por lo menos un producto natural o sintético, preferiblemente un compuesto natural, cuyo producto natural o sintético comprende en su estructura por lo menos un grupo fenol o alcohol, que opcionalmente tiene una o más cadenas hidrofóbicas, o por lo menos un grupo esterol.En un segundo aspecto, la presente invención se refiere a la utilización de dicha preparación enzimática acuosa aislada en la funcionalización de la superficie del papel o soportes celulósicos.
