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.
