Provided herein are isolated laccase enzymes and nucleic acids encoding them. Also provided are mediators for laccase reactions. Also provided herein are methods for using laccases to oxidize lignins and other phenolic and aromatic compounds, such as for bio-bleaching and decolorization of wood pulp under high temperature and pH conditions to facilitate a substantial reduction in use of bleaching chemicals, as well as for treatment of fibers.
L'invention concerne des enzymes laccases et des acides nucléiques codant celles-ci. L'invention concerne également des médiateurs pour des réactions de laccases. L'invention concerne en outre des procédés d'utilisation des laccases pour l'oxydation des lignines et d'autres composés phénoliques et aromatiques, par exemple, pour le blanchiment biologique et la décoloration de la pâte de bois à des températures élevées et dans des conditions de pH déterminées, afin de faciliter une réduction sensible dans l'utilisation de produits chimiques de blanchiment, ainsi que pour le traitement des fibres.
