Extracellular proteases and laccases produced by Pleurotus ostreatus PoB: the effects of proteases on laccase activity.

Laccases are enzymes produced by plants and white rot fungi, such as Pleurotus ostreatus, with industrial applications. Fungal laccases have been widely studied, and investigations, such as those involving recombinant DNA technology or adding inducers, have been made to increase laccase production. On the other hand, it has been proposed that extracellular proteases could decrease laccase activity when both types of enzymes are produced by P.
