STUDY ON THE THERMOKINETIC PROPERTIES OF BACTERIAL-GROWTH

The power-time curves of bacterial growth at different temperatures we re determined by using the 2277 Thermal Activity Monitor (Sweden). Fro m these curves, the growth rate constant (mu) and activation energy (E -a) were calculated. According to the transition state theory of react ion dynamics, the activation entropy (Delta S double dagger), activati on Gibbs free energy (Delta G double dagger) and equilibrium constant (K double dagger) of the activation state could be calculated. These r esults permitted thermodynamic analysis of the bacterial growth metabo lism.
