发明名称 LACCASES FOR BIO-BLEACHING
摘要 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.

主权项 1. An isolated polypeptide, comprising: an amino acid sequence having at least 80% sequence identity to the amino acid sequence of SEQ ID NO: 4, wherein said isolated polypeptide comprises laccase activity, oxidizes lignin under conditions of pH greater than or equal to pH 8.0, and retains laccase activity for greater than at least about 5 minutes at greater than or equal to 60° C.
