Abstract:

The growth thermograms of variation strains of Escherichia coli and Salmonella typhi were studied using LKB 2277 Bioactivity Monitor. The results showed that the changes of the growth thermograms of bacterial variation strains are related to the variation of bacteria. Variation strain which is positive or negative for the same substrate can be distinguished obviously by their growth thermograms if medium is suitably chosen.

Key words: Bacterial variation, Growth thermogram, Microcalorimetry
