Glucose-2-oxidase activity in mycelial cultures of basidiomycetes

Abstract
The activity of intracellular glucose-2-oxidase was tested in 40 species of 26 basidiomycete genera. The enzyme catalyzing the oxidation of D-glucose to the dicarbonyl sugarD-arabino-2-hexosulose was demonstrated in mycelial extracts of 9 species ofAphyllophorales and 6 species ofAgaricales cultivated in liquid media. In the majority of species exhibiting this activity hexosulose was detected in the cultivation medium. The highest enzyme activity was detected inOudemansiella mucida, Coriolopsis occidentalis, Fomes fomentarius, Trametes versicolor and a not-yet-classified species of the genusTrametes.
