Process for macromolecularizing phenolic compounds etc. and use thereof

A method of protecting and strengthening wood through polymerization of one or more phenolic compounds or one or more aromatic amine compounds with an enzyme having polyphenol oxidizing activity, said method comprising

• impregnating wood with an enzyme having polyphenol oxidizing activity,
• allowing polymerization of one or more phenolic compounds or one or more aromatic amine compounds already present in the wood by said enzyme at an alkaline pH, and
• recovering the protected and strengthened wood.

A method of protecting and strengthening wood through polymerization of one or more phenolic compounds or one or more aromatic amine compounds with an enzyme having polyphenol oxidizing activity, said method comprising

• impregnating wood with a combination comprising an enzyme having polyphenol oxidizing activity, one or more phenolic compounds or one or more aromatic amine compounds, and one or more thermal curing agents selected from the group consisting of a quinone compound, an unsaturated fatty acid, an unsaturated alcohol, and an unsaturated alkyl compound,
• allowing polymerization of the one or more phenolic compounds or the one or more aromatic amine compounds in the wood by said enzyme at an alkaline pH, and
• recovering the protected and strengthened wood.

A method of protecting and strengthening wood through polymerization of one or more phenolic compounds or one or more aromatic amine compounds with an enzyme having polyphenol oxidizing activity, said method comprising

• impregnating wood with a combination comprising an enzyme having polyphenol oxidizing activity, one or more phenolic compounds or one or more aromatic amine compounds, and a physiologically active substrate selected from the group consisting of an antimicrobial compound, antiviral composition, an insecticidal compound and a biotic repellent metal ion,
• allowing polymerization of the one or more phenolic compounds or the one or more aromatic amine compounds in the wood by said enzyme, and
• recovering the protected and strengthened wood.
