VERFAHREN ZUR DELIGNIFIZIERUNG VON LIGNOCELLULOSEHALTIGEM MATERIAL, BLEICHE UND BEHANDLUNG VON ABWAESSERN MITTELS LACCASEN MIT ERWEITETER WIRKSAMKEIT

摘要

The invention concerns a process for the removal of lignin from lignocellulose-containing material, the bleaching of lignocellulose-containing material (i.e. the enzymatic de-inking of recycled paper) and/or the treatment of waste water arising from the manufacture of paper or cellulose. The process uses laccase enzymes obtained from Coriolus versicolor or other laccase producers, at the same time adding or metering in non-aromatic redox agents plus phenolic and/or non-phenolic aromatic redox compounds, the phenolic and non-phenolic units of the lignin either being oxidized directly by the action of these phenolic and/or non-phenolic aromatic compounds, or the lignin being oxidized by other phenolic and/or non-phenolic compounds produced by the oxidizing action of these compounds.
