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.
