Abstract

In enzymatic breakdown and bleaching of lignin from chemically (e.g. with NaOH) and/or mechanically pre-treated material, e.g. lignocellulose, lignin materials, lignin-contg. liquors and waste waters, and lignin, for prodn. of pulp, cellulose or lignin breakdown prods., by addn. of lignolytic enzymes and microorganisms and oxidising agents, enzyme-activating salts, and phenolic cpds., the lignin is degraded from lignocellulose or lignin material, or lignin by addn. of lignolytic enzymes and/or lignolytic bacteria or moulds, in presence of oxidising and reducing agents and/or salts and/or phenolic cpds., the lignocellulose or lignin material, liquor or waste water, or lignin is bleached in 1 or more stages.
