There are many different enzymes that are involved in the decay of wood by white-rot fungi, some of which directly oxidize lignin. The relative abundance of phenylpropane alkyl side chains of lignin characteristically decreases when decayed by white-rot fungi. It has been reported that the oyster mushroom ("Pleurotus ostreatus") preferentially decays lignin instead of polysaccharides. This is different from some other white-rot fungi, e.g., "Phanerochaete chrysosporium", which shows no selectivity to lignocellulose.
