Table 2 Decolorization percentages for different synthetic organic dyes obtained by Leptosphaerulina sp. laccase (100 mU) alone or in the presence of acetosyringone (AS), syringaldehyde (SYR), methyl-syringate (MS) or HBT as redox mediators (mediator/dye ratio = 2) after 4 h of treatment

From: Identification and characterization of laccase-type multicopper oxidases involved in dye-decolorization by the fungus Leptosphaerulina sp.
