Lignin peroxidases and Mn peroxidases are known to catalyze the initial depolymerization of the lignin polymer. The ligniolytic system of Phanerochaete chrysosporium is activated during secondary metabolism of fungal growth and is regulated by the availability of nutrients, oxygen, and trace metals and the pH. Several aromatic substrates and degradation products of lignin have been assayed for their ability to increase ligninolytic activity. Of the aromatic compounds tested, veratryl alcohol is the most effective. This study examines the mechanism by which veratryl alcohol increases lignin peroxidase activity. Results indicate that veratryl alcohol acts by protecting the enzymes and does not act via an induction mechanism. 25 refs., 6 figs., 1 tab.
