Effect of aqueous extracts from Ceriporiopsis subvermispora-biotreated wood on the decolorization of Azure B by Fenton-like reactions

► Study on the effect of wood extracts on the decolorization of a dye by the Fenton reaction. ► Aqueous extracts from biotreated wood exhibit Fe3+- and Cu2+-reducing activity. ► Aqueous extracts (0.1% v/v) stimulated the dye decolorization using Fe3+ and H2O2.
