PROCESS, USING ENHANCED-ACTION LACCASE ENZYMES, FOR THE DELIGNIFICATION OR BLEACHING OF LIGNOCELLULOSE-CONTAINING MATERIAL OR FOR THE TREATMENT OF WASTE WATER

摘要

The present invention relates to a process for the degradation of lignin from material containing lignocellulose and/or bleaching of material containing lignocellulose for enzymatically deinking waste paper and for treating pulp and paper mill waste, whereby laccases obtained from Coriolus versicolor and other laccase formers are used by simultaneously adding and/or apportioning non-aromatic reducing and oxidizing agents as well as such phenolic compounds and/or non-phenolic aromatics which either oxidize the phenolic and non-phenolic lignin structures directly through the effect of these phenolic and/or non-phenolic aromatics or which oxidize the lignin through oxidation brought about by these compounds of further phenolic and/or non-phenolic compounds.
