Determination of thermograms of bacterial growth

The fundamental growth thermograms of bacteria have been determined by using the microcalorimetric method. These perfect thermogram curves reflect the changes of bacterial growth patterns (including the lag phase of growth, log growth, stationary phase and the decline phase of growth). In our experiments, highly characteristic and reproducible growth patterns are observed under the same condition, therefore one can use these thermograms as "finger print" to discriminate bacteria. On the other hand, there thermogram curves contain ample information, which are very significant for the studies on microorganism metabolism, bio-thermokinetic and clinical fields.
