Using Ancrocalorimetric method, the thermally measured curves of differenttypes of metabolism of E. coli were detendned. nom these thermal measured cu-rves, wecan obtain the heat output of E. coll at growth metabolism to be 1 .74+10.63 pW.cell- 1; and0.14+0.04 pW.cell-1 at the non-growth metabolism while at the endogenous metabolismit is 0.045+0.001 pW.
The finite growth of Escherichia coli was studied by using a LKB 2277 BioActivityMollitor. We found that the finite growth is a nonliear dynanic process. The nonlinear dynamicbehaviour in the finite growth process and the monlinear dymanic models describing the processwere discovered and established. The curve of logistic map corresponding to the finite growththermogram of Escherichia coli was obtained and the nonilnear dynamin parameters were calculated by means of a computer. Moreover. we also discussed the nonlinear dynamic characters ofEscherichia colt in its finite growth process.
The thermograms of Brucalles Br.10 and Br-981 have been deterAnned. From the thermograJns, a thermokinetic equation ln =lnb - kt could be established for the liAnted growth of bacteria. From this equation, the growth constant k, the intial growth rate 6, 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 bacteriaJ growth and their characteristics.
