Bleaching of Dyes with Laccases
The purpose of this work is to investigate the decoloration and bleaching of various kinds of dyes in aqueous solutions and on fabrics with one of the oxidoreductases, laccase. The twenty-two water-soluble dyes of azo, anthraquinone, acridine, triphenylmethane, and indigo types were employed. In addition bleaching effect of denim cotton fabrics dyed with indigo was also examined. The two laccase preparations from Trametes villosa and Trametes sp. were utilized.
