摘要

A major laccase isozyme from Grifola frondosa (Lac 1) was found to be effective for decolorizing of synthetic dyes and degrading of bisphenol A. The oxidative capability of Lac 1 toward synthetic dyes and bisphenol A was enhanced in the presence of the redox mediator, 1-hydroxybenzotriazole. The major product from the degradation of bisphenol A by Lac 1 was determined to be 4-isopropenylphenol.
