Hexosaminidase, β-N-acetylhexosaminidase; endonuclease, DNA/RNA endonuclease; endoglucanase, endo-1,4-β-d-glucanase. Data expressed as percentage of the control. The values indicate the means of triplicate experiments (± standard error). Statistical analysis, two-way ANOVA followed by Holm-Sidàk post hoc test.
