    DK-2880 Bagsvaerd‚ Denmark. Abstract Diferulic acid forms cross-links in naturally occurring plant cell wall polymers such as arabinoxylans and pectins. We have used model ethyl esterified substrates to find enzymes able to break these cross-links. A tannase from Aspergillus oryzae exhibited esterase activity on several synthetic ethyl esterified diferulates. The efficiency of this esterase activity on most diferulates is low compared to that of a cinnamoyl esterase‚ FAEA‚ from Aspergillus niger. Of the
