Abstract:

By using an LKB2277 Bioactivity Monitor, we have determined the thermogenesis power curves of four kinds of Brucellas S2(55007), M5 (55009),83-202,83-980. And established the thermokinetic equation for the process of cell growth inhibited by the products of metabolism, as:
Ln[1/(β﹒Pt)-1]=ln[1/(β﹒P0)-1]-k0﹒t
From this equation, the rate constants of cell growth k [= k0(1 - β﹒P0)] were obtained. This thermokinetic equation is very suitable for cell growth of separated culture and is very important for the study of bacterial limited growth and their characteristics.

Key words: Bacterial growth, Microcalorimetry, Thermokinetics, Thermochemistry
