Abstract

The pathways for syringic acid metabolism have been studied in detail for the white-rot fungus and a reaction sequence proposed. According to identified metabolites the following reactions occur: reduction of the carboxyl group; hydroxylation and simultaneous decarboxylation; demethylation; and methylation of the -hydroxyl group. In the two soft-rot fungi and rapid metabolism of syringic acid was observed and the medium was depleted of the acid within 12 h. The formation of 3,4,5-trimethoxybenzoic acid indicates an ability within the soft-rot fungi also to methylate the -hydroxyl group. The two brown-rot fungi and were poor metabolizers of syringic acid. However, demethylation was observed with and an unidentified product appeared in the culture solution of
