Abstract
Vanillic acid metabolism was studied in wild-type Sporotrichum pulverulentum and three different mutants. Vanillic acid was found to be oxidatively decarboxylated to methoxyhydroquinone (MHQ) and simultaneously reduced to vanillin and vanillyl alcohol to different degrees depending upon the cultivation conditions. The reducing pathway cannot be utilized unless the fungus has access to an easily metabolized carbon source such as glucose or cellobiose, while decarboxylation takes place in cultures with only vanillic acid present. Polymerization reactions also occurred in the culture solutions. Some evidence for reoxidation of vanillin and vanillyl alcohol was obtained in vivo, and in vitro experiments using horseradish peroxidase.
Using vanillic acids labelled in the carboxyl, methoxyl and the aromatic ring it was shown that decarboxylation occures before ring-cleavage, which in turn takes place earlier than the release of 14CO2 from O14CH3-vanillate. The 14CO2 evolution from the methoxyl group is repressed by 1% cellobiose as compared to 0.25% cellobiose, but is stimulated by 26 mM nitrogen (as asparagine plus NH4NO3) compared to 2.6 mM nitrogen. Since S. pulverulentum appears to require three hydroxyl groups attached to the benzene ring before ring-cleavage can occur, preparation for ring-cleavage is apparently achieved by hydroxylation rather than by demethylation.
A scheme for metabolism of vanillic acid by S. pulverulentum based upon these results is proposed.
