Inhibition of the chitinase activity of S. griseus and RGSM chitinase by anti-peptide Ab. Chitinolytic activity was measured as described in Schuttelkopf et al. [23]. 0.2 µg·µL⁻¹ of S. griseus chitinase (white bars) and 30 µg of RGSM (grey bars) were assayed in the presence of increasing concentrations of anti-peptide Ab. Different letters assigned to means designate a statistical difference regarding data from S. griseus (not italic letters), or from RGSM samples (italic letters).
