Enzymatic decolorization of synthetic organic dyes. Decolorization curves for Methyl Orange (black lines), Acid Blue 74 (grey lines) produced by Leptosphaerulina sp. laccase alone (−x-) and in the presence of S-type natural mediators. 50 uM dye and 100 μM redox mediator were used (AS: acetosyringone -■-; SYR: syringaldehyde-▲-; MS: methyl syringate -●-)
