Abstract

Selected species of Basidiomycetes (Abortiporus biennis, Cerrena unicolor and Trametes versicolor) were known to produce enhanced extracellular laccase (benzenediol:oxygen oxidoreductase, EC 1.10.3.2) when they exposed to some heavy metal ions, xenobiotics and lignin related compounds. The constitutive and inducible forms of purified laccase showed oxidative and demethoxylating activities, which prove the bifunctionality of the enzyme. The oxidative/demethoxylating ratios in inducible laccases varied depending on used inducers. The demethoxylating activities of laccases induced by lignin related compounds were much higher than those induced by various xenobiotic substances.
