Oxidation of syringic acid by extracellular peroxidase of white-rot fungus, Pleurotus ostreatus

, : Oxidation of syringic acid by extracellular peroxidase of white-rot fungus, Pleurotus ostreatus. Mycoscience 36(1): 31-35

The oxidative degradation of syringic acid by the extracellular peroxidase of Pleurotus ostreatus was studied. Three products formed in the oxidation of syringic acid by the peroxidase in the presence of O-2 and H-2O-2 were identified as 2,6-dimethoxyphenol, 2,6-dimethoxy-1,4-dihydroxybenzene, and 2,6-dimethoxy-1,4-benzoquinone. A free radical was detected as the reaction intermediate of the extracellular peroxidase-catalyzed oxidation of acetosyringone. These results can be explained by mechanisms involving the production of a phenoxy radical and subsequent decarboxylation. This is the first time that 2,6-dimethoxyphenol has been identified in extracellular peroxidase-catalyzed reactions.
