Abstract

Phenolic and nonphenolic (permethylated) synthetic [14C]lignins were depolymerized by Trametes villosa laccase in the presence of a radical mediator, 1-hydroxybenzotriazole (HOBT). Gel permeation chromatography of the treated lignins showed that ~10% of their substructures were cleaved. The system also cleaved a β-O-4-linked model compound, 1-(4-ethoxy-3-methoxy-ring-[14C]phenyl)-2-(2-methoxyphenoxy)-propane-1,3-diol, and a β-1-linked model, 1,2-bis-(3-methoxy-4-[14C]methoxyphenyl)-propane-1,3-diol, that represent nonphenolic substructures in lignin. High performance liquid chromatography of products from the oxidized models showed that they were produced in sufficient yields to account for the ability of laccase/HOBT to depolymerize nonphenolic lignin.
