Abstract

Foreliggende oppfinnelse vedrører en fremgangsmåte for nedbrytning av ligning fra llgnocelluloseholdlg materiale og/eller bleklng av llgnocelluloseholdlg materiale for enzymatisk avfarglng av returpapir og for behandling av splllvann fra paplrfremstllllng og fremstilling av kjemisk masse, hvorved fra Corlolus verslcolor og andre laccasedannere utvunnede laccaser anvendes under samtidig tilsetning og/eller tlldosering av Ikke-aromatlske reduksjons- og oksydasjonsmidler samt silke fenollske forbindelser og/eller ikke-fenollske aromater som enten direkte oksyderer de fenollske og Ikke-fenollske strukturene av llgnlnet ved virkningen av disse fenollske og/eller Ikke-fenollske aromatene eller oksyderer lignlnet ved hjelp av ved disse forbindelsene formidlet oksydasjon av ytterligere fenollske og/eller Ikke-fenollske forbindelser.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a process for breaking down equation from lignocellulose-containing material and / or bleaching of lignocellulose-containing material for enzymatically decolorizing recycled paper and for treating waste water from papermaking and producing chemical pulp, using and / or target dosage of Non-aromatic reducing and oxidizing agents as well as silk phenolic compounds and / or non-phenolic aromatics which either directly oxidize the phenolic and non-phenolic structures of the solvent by the action of these phenolic and / or non-phenolic aromatics or oxidizers oxidized by further phenolic and / or non-phenolic compounds mediated by these compounds.
