Figure 3: Enzymatic activity of cellulase (FPAse), endochitinase (chit42), NAGase (nag1), β-1,3-glucanase (gluc83), Lipase (lip1), Acid phos phatase (ap1) after 24, 48 and 72 hours of incubation of T. reesei (TU-6), T. reesei (gna1QL) and T. reesei (Δgna1) with P. ultimum cell wall as the carbon source. Enzyme activity was assayed by the colorimetric method as indicated in the materials and methods section. In all cases, the standard deviation values were smaller than 5% of the mean values of triplicate.
