摘要：

The degradation pathway of vanillyl and veratryl alcohol by Lentinus edodes extracellular enzymes was studied. In both cases several products of side chain oxidation and aromatic ring cleavage were isolated and characterized. We have observed that the products from veratryl alcohol degradation by Lentinus edodes are quite different from those isolated from incubations with other white-rot fungi which have veraraldehyde as the major product, in fact, this compound is not produced as final metabolite in L. edodes incubations. This behaviour could explain the apparent absence of lignin peroxidase and veratryl alcohol oxidase activities in L. edodes cultures, since such activities are usually measured by monitoring veratraldehyde formation during the veratryl alcohol oxidation; thus, it is suggested that additional assay methods should be developed, with preferably direct observation of aromatic ring oxidation products.
