Each value is a mean of three observations. Values followed by different letters differ significantly at p ≤ 0.05 using MstatC software.
K_d= First order rate constant for inactivation;
∆H* (kJ/M)= E_a (57 kJ/M)-RT where E_a is activation energy;
∆G* (kJ/M)= -RT ln {(k_d.h)/k_B.T)};
∆S* is entropy of irreversible inactivation and was calculated from ∆S = (∆H*- ∆G*) /T.
