The power-time curves of the growth of three strains of petroleum bacteria at different temperatures have been determined. A novel equation of a power-time curve has been proposed in this paper. The general formula to calculate the rate constant of the bacterial growth has been derived. The rate constants of the bacterial growth at different temperatures, the heat production per newly formed bacterium, the bacterial number at the end of the bacterial growth and the deceleration rate constant of the bacterial growth at 50.00°C, have been calculated. The optimum growth temperatures of the three strains have been obtained.

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.

The thermal curves ofB. subtilis andP. atruginosa were determined by using a 2277 Thermal Activity Monitor (Sweden). Under inhibitory conditions, an experimental model of
bacterial growth was established. The growth rate constant (μ), deceleration rate constant (β) and optimum temperature (T) of bacterial growth were calculated.
