Abstract
The spore laccase of Bacillus amyloliquefaciens LS01 was evaluated for its ability in decolorization of different synthetic dyes. The decolorization process was not efficient by the laccase alone. The addition of mediators could remarkably improve the efficiency of dye decolorization. Remazol Brilliant Blue R and reactive black 5 were resistant to decolorization for most mediators. Acetosyringone was proved to be the best mediator for the spore laccase, and a decolorization of 63−82% was achieved for all the tested dyes in the presence of acetosyringone. The results indicate that the spore laccase-mediator system could be used for the treatment of industrial dye effluents.
