Abstract:

The thermograms of Brucalles Br﹒10 and Br﹒981 have been determined. From the thermograms, a thermokinetic equation ln|[(P/Pmax)1-m-1]| =lnb - kt could be established for the limited growth of bacteria. From this equation, the growth constant k, the intial growth rate b, the mean specific growth rate k/m, and the mean thermal power increasing rate Pmaxk/(2m + 2) were calculated. This equation is very significant for the study of bacteria growth and their characteristics.

Key words: Bacterial growth, Microcalorimetry, Thermokinetics
