<Original>Arylglycerol Formation in Degradation of β-O-4 Lignin Substructures with and without α-O-γ Bond by Phanerochaete chrysosporium

Abstract

Hydrogen (deuterium) atoms at C_α and C_β positions of β-O-4 lignin substructure model compounds with and without α-O-γ bond were found to be retained at Ca and Cp positions of arylglycerol in degradation by Phanerochaete chrysosporium. It was accordingly proved that any compound which lost deuterium atoms at C_α and/or C_β positions (e.g. α- and/or β-keto derivatives) is not the intermediate compound to give the arylglycerol.
