Abstract

SUMMARY: The degradation of sinapic acid, a monomer of hardwood lignins, by the yeast was studied. Syringic acid, 3--methyl gallic acid, gallic acid and 2,6-dimethoxy-1,4-benzoquinone were identified as degradation products. Glucose was shown to be required for the demethylation of the methoxy groups on the ring. Unlike in the bacterium , ring cleavage seemed to occur via gallic acid and not via methyl gallic acid. Cell-free oxidative decarboxylase (hydroxylase) activity was detected; this enzyme might be ultimately responsible for the formation of dimethoxyquinone.
