Abstract

A method is described for distinguishing between white-rot fungi producing laccase (EC 1 · 10 · 3 · 2) and brown-rot fungi producing catechol oxidase (EC 1 · 10 · 3 · 1). Laccase oxidizes a redox indicator ABTS (2, 2'-azino-di(3-ethylbenzothiazoline-6-sulfonic acid)) to form a blue-green cation radical whilst catechol oxidase does not. The method is suitable for detecting laccase excreted by mycelia growing on agar and wood-based substrates, and proteins derived from culture liquids after electrophoretic separation on polyacrylamide gel. The method can be adapted for quantitative estimation by spectrophotometry.
