Power-time (p-t) curve profiles and relationships between the p-t curves and viable cell counts when Escherichia coli NTCT 10418 was grown in two different broth media, were studied by flow microcalorimetry. Data obtained from a total of twenty six experiments and expressed by arithmetic means are presented and analysed. The increase in viable cell numbers did not accompany linear power output, but exhibited a stepwise pattern similar to that observed in a synchronous bacterial culture during the exponential phase of growth. Some possible explanations for this are discussed.
