This invention relates to methods of oxidizing a substrate in the presence of a laccase or a laccase related enzyme and an enhancing agent. More specifically, the invention relates to a method of bleaching of dye in solutions, to a method of inhibiting the transfer of a textile dye from a dyed fabric to another fabric when said fabrics are washed together in a wash liquor, to a method of bleaching of lignin- containing material, in particular bleaching of pulp for paper production, to a method of treatment of waste water from pulp manufacturing, and to a method of enzymatic polymerization and/or modification of lignin or lignin containing material.
L'invention concerne des procédés d'oxydation d'un substrat en présence d'une laccase ou d'une enzyme apparentée à une laccase et d'un agent de renforcement. Plus particulièrement, l'invention concerne un procédé de blanchiment de colorant dans des solutions, un procédé d'inhibition du transfert d'un colorant de textile depuis un tissu coloré vers un autre tissu quand lesdits tissus sont lavés ensemble dans un bain détergent, un procédé de blanchiment d'une matière contenant de la lignine, notamment de blanchiment de pâte de cellulose pour la fabrication de papier, un procédé de traitement d'eaux usées provenant de la fabrication de papier, ainsi qu'un procédé de polymérisation et/ou de modification enzymatiques de lignine ou de matière contenant de la lignine.
