WebInactivation Alcalase can be inactivated in 30 minutes at 50C (122F) or higher when the pH is 4, and in 10 minutes at 85C (185F) or higher when the pH is 8. However, the inactivation is very much dependent on the substrate (substrate concentration, pH, etc.). WebThe most stabilized Alcalase-glyoxyl derivative was produced using 96 h of immobilization time and high activation grade of the support. It presented half-life of ca. 23 h, at pH 8.0 and 63 degrees C and was ca. 500-fold more stable than the soluble enzyme. Thermal inactivation of all derivatives followed a single-step non-first-order kinetics.
