Cellulolytic Activity of Three Fusarium culmorum (W. G. Sm.) Sacc. Isolates Pathogenic towards Wheat Seedlings

Fusarium culmorum isolates pathogenic to wheat (severely, medium and weakly pathogenic) proved to be producers of endo-1,4-β-glucanase and exo-1,4-β-glucanase. The activity of the latter enzyme was low. There was no correlation between the activities in vitro of the two enzymes and pathogenicity of the isolates.
