All values were calculated as average of 3 sets of experimental replicates and were considered statistically significant with p < 0.005. Arrhenius energy (Ea) of activation was calculated by plotting the ln k where k is rate constant at each temperature against reciprocal of temperature (1/T) in kelvin.
