Figure 5. Arrhenius plots for calculating enthalpy and entropy for reversible inactivation of β-xylosidase. They were calculated by applying the equation 2 in Materials and Methods (Aiba et al. 1973).

The value of ∆H* was calculated from slope of the straight line between ln(kd /T) and 1/T while ln(kB/h)+ ∆S*/R=Intercept on ordinate. kB, h, and R are 1.38 x 10-23 JK-1, 6.63 x10-34 J.S and 8.314 JK-1 mol-1 respectively (Rahsid and Siddiqui, 1998).
