Oxidative, Reductive, Hydrolytic and Other Enzymatic Systems for Oxidizing, Reducing, Coating, Coupling or Cross-Linking Natural and Artificial Fiber Materials, Plastic Materials or Other Natural or Artificial Monomer to Polymer Materials

摘要

The invention relates to methods for oxidizing (redox reactions, preferably pulp delignification/bleaching), for carrying out coupling reactions (grafting polymer materials) or for carrying out cross-linking reactions on natural (i.e. having natural origin) or artificial (i.e. synthetically produced polymers) monomers to polymers or of mixtures of natural and artificial polymers or of fibre materials, of lignocellulose-containing, cellulose-containing or protein-like natural polymers or fibre materials such as pulp, textiles like cotton and wool. The invention is characterized in that 1) these oxidation, coupling or cross-linking reactions are carrying out using hydrolases such as lipases, esterases, proteases, amidases, transferases, acylases, glycosidases or glycotransferases or oxidoreductases, such as preferably peroxidases, chloroperoxidases and laccases, either individually or in combination with one another; and 2) that these reactions ( oxidation, coupling or cross-linking reactions) are carrying out with the above mentioned substances and/or with property-changing substances such as monomer to polymer substances (natural or synthetic) either simultaneously or one after the other using specific enzyme-activated enhancer substances and/or coupling substances.
