Three types of enzyme assays were conducted to
determine cellulase activity. The results showed that
OL recorded the highest activity for endoglucanase,
while PC recorded the lowest (Figure 4). Exoglucanase
activity remained high in all four species. There were no
significant differences among them according to ANOVA.
The reading for β-glucosidase was overall low for all
four species, nevertheless, OL showed the highest activity
for this enzyme. All white rot basidiomycetes degrade
wood polymers cellulose, hemicellulose and lignin at
different rates.
