Epoxy ceriporic acid produced by selective lignin-degrading fungus Ceriporiopsis subvermispora

► Selective white rot fungus, Ceriporiopsis subvermispora produces unique lipid-related metabolites in wood decay. ► Epoxidized alkylitaconic acid (ceriporic acid) was isolated and identified. ► The metabolite reflects oxidative environments in wood decay. ► This is the first report of natural epoxy alkenylitaconic acid.
