Table 5. Thermodynamic parameters estimated by Arrhenius approach for batch formation and deactivation of CBH by cultures of Cellulomonas flavigena. Thermodynamic parameters were determined using following equation: Ln (q_{p} /T) = Ln(k_{B}/h)+ ∆S^{*}/R∆H^{*}/R.1/T ; where q_{p}, T, k_{B} , h, ∆S^{*}, ∆H^{*} and R are specific productivity, absolute temperature, Boltzmann constant, Planck's constant, entropy of activation, enthalpy of activation and gas constant respectively. The values of k_{B} , h, and R are 1.38x10^{23} J.K^{1}, 6.63 x 10^{34} J.s and 8.314 J/.K^{1}.mol^{1} respectively. ∆H^{*} was calculated as slope and Ln(k_{B}/h)+ ∆S^{*}/R as intercept on Yaxis using Figure 2b.
