The bacterial growth thermogram curves under different acidities were determined. From these thermogram curves, the growth rate constants(k) at different acidities were calculated and the equation correlating of k with PH could be established. From these k-pH equations,the optimum acidity of bacteria growth could be obtained. These models provide a good method for the study of the metabolism of bacteria.

Key words: Bacteria, Microcalorimetric method, Optimum acidity of bacteria growth
