Biodegradation of bisphenol A and decolorization of synthetic dyes by laccase from white-rot fungus, trametes polyzona
Purified laccase from Trametes polyzona WR710-1 was used as biocatalyst for bisphenol A biodegradation and decolorization of synthetic dyes. Degradation of bisphenol A by laccase with or without redox mediator, 1-hydroxybenzotriazole (HBT) was studied. The quantitative analysis by HPLC showed that b...
