Bacterial growth power-time curves were determined with a 2277 Thermal Activity Monitor. Bacterial multiplication curves were measured at different temperatures and an experimental model was established. Both growth rate constants and lowest growth temperatures were calculated.

The power-time curves of bacterial growth at different temperatures were determined by using the 2277 Thermal Activity Monitor
(Sweden). From these curves, the growth rate constant (μ) and activation energy (Ea) were calculated. According to the transition state theory of reaction dynamics, the activation entropy (ΔS≠), activation Gibbs free energy (ΔG≠) and equilibrium constant (K≠) of the activation state could be calculated. These results permitted thermodynamic analysis of the bacterial growth metabolism.

The power-time curves ofS. flexneri 6,S. flexneri 3b,S. dysenteae andE. coli were determined by using the 2277 Thermal Activity Monitor (Sweden). From these curves, by using a microorganism growth experimental
model with inhibitory conditions, the growth rate constant (μ) was determined at different medicinal concentrations, with
the optimum allowable concentration of the synthetic medicine.

Bacterial growth power-time curves were determined by using the 2277 Thermal Activity Monitor. The growth rate constants at
different temperatures and acidities were calculated via the optimum growth temperature and optimum growth acidity obtained.
