Decomposition of 14C-Labelled Vanillic Acid and its Related Compounds by Fusarium oxysporum

Abstract

Summary The decomposition of vanillic, veratric and benzylvanillic acid by submerged cultures of Fusarium oxysporum 27 was studied. Using vanillic acid specifically 14C-labelled either in the methoxyl, the carboxyl or the aromatic ring, it was shown that the release of 14CO2 from the carboxyl and aromatic ring reached a peak more rapidly than the release from the methoxyl-labelled vanillic acid. The evolution of 14CO2 from vanillic, veratric and benzylvanillic acid, especially from the ring-labelled vanillic acid, was strongly inhibited by cellulose at a concentration of 10 g/l.
