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