Proposed predominant linkages targeted by fungal action. For simplicity, only the most abundant β-O-4′alkyl-aryl-ether linkage is shown, where dotted lines represent –H or –OCH₃ and wavy lines indicate main positions of further coupling. Cs Ceriporiopsis subvermispora, Pe Pleurotus eryngii, Le Lentinula edodes. Cs C_β–O–aryl cleavage, Le/Pe C_α–C_β cleavage
