Induction of laccase by metal ions and aromatic compounds in Pleurotus ostreatus HAUCC 162 and decolorization of different synthetic dyes by the extracellular laccase
Extracellular laccase activity was stimulated by metal ions or aromatic compounds. Synergistic stimulation by metal ions and aromatic compounds on laccase was observed. Transcript levels of laccase gene family under different stimulations were studied. The crude extracellular laccase could efficiently degrade different synthetic dyes.
