A multicomponent system for use in detergent substances consists of oxidation catalysts and suitable oxidizing agents and aliphatic, cycloaliphatic, heterocyclic or aromatic compounds containing NO, NOH or (A).

Multicomponent bleaching system

Multi-component system for modifying, degrading or bleaching lignin, lignin-containing materials or similar substances, includes (a) if appropriate at least one oxidation catalyst; (b) at least one suitable oxidizing agent; and (c) at least one mediator, wherein the mediator is chosen from the group consisting of N-aryl-N-hydroxyamides.

Process for the production of lignolytic enzymes by means of white rot

Process for the production of lignolytical enzymes by means of

A process and an apparatus capable of removing and/or transforming lignin or its degradation products present in material containing lignocellulose. In the present process, a redox potential is set between 200 and 500 mV by the addition to an acid aqueous solution, which contains lignitic raw materials, of oxidizing agents and/or reducing agents and/or salts and/or phenolic compounds. The lignin degrading reaction and its attendant simultaneous bleaching effect is initiated by the addition of enzymes, microorganisms, animal or plant cells. Continuous stirring allows the reaction to be maintained for several hours at a value that fluctuates about a constant redox potential value, and a constant temperature.
