The biodegradation of dyes in textile wastewater is nowadays a subject of intensive research. In particular, a biotransformation of various dyestuffs by white-rot fungi is the most promising alternative. This study provides the results of decolorization of the aqueous solution of azo- and anthraquinone dyes by the laccase complex from Cerrena unicolor. The investigations were carried out using 3 systems: with active biomass, with sterilized biomass (biosorption), and with secretion of enzymatic complex. The enzymatic biotransformation gave to 97% decolorization of Acid Blue 62 and 95% decolorization of Reactive Blue 81 after 15 min. The dye?s adsorption on mycelia contributes substantially (30-40%) to decolorization of the textile wastewater.
