Abstract:


 By using an LKB-2277 Bioactivity Monitor, we have determined the thermogenesis curves of two species of Brucellas arithmetic series growth. From the thermogenesis curves, a thermokinetic equation as:
dP/dt=km﹒Pn
could be established for bacterial arithmetic series growth in which the order of growth metabolism n=0. The mean specific rate constant of multiplication μand the mean generation time G et al. were calculated. This model was compared with the exponential model.

Key words: Bacterial growth, Microcalorimetry, Thermokinetics, Thermochemistry
