Enzymatic determination of veratryl alcohol

A rapid and sensitive method was developed for the measurement of veratryl alcohol--a secondary metabolite of some lignin degrading fungi. The method is based on the enzymatic oxidation of veratryl alcohol to veratraldehyde by the ligninase of Phanerochaete chrysosporium. The purified Enzymes oxidized veratryl alcohol completely to veratraldehyde (75%) and some unidentified products. The enzymatic method was applied to measure veratryl alcohol in the culture filtrates of Chrysosporium pruinosum and it gave the same results as the conventional method involving extraction and separation by high-pressure liquid chromatography. Benefits and limitations of the method are discussed.
