Abstract:

Using microcalorimetric method, the thermally measured curves of different types of metabolism of E. coli were determined. From these thermal measured curves, we can obtain the heat output of E. coli 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﹒cell-1

Key words: Escherichia coli, Growth metabolism, Non-growth metabolism, Endogenous metabolism, Power of metabolism
