<Original>Aromatic Ring Cleavage of Various β-O-4 Lignin Model Dimers by Phanerochaete chrysosporium

Abstract

In the degradation of β-O-4 lignin model dimers with different aromatic substituents on β-etherated aromatic ring by intact cells of Phanerochaete chrysosporium, esters of arylglycerol, cyclic carbonates, formate and methyl oxalate, were formed as aromatic ring cleavage products of the models. Substituents of aromatic nuclei considerably influenced the formation of aromatic ring cleavage products and O-C_4 cleavage product, arylglycerol.
