Microcalorimetric study of the anaerobic growth of Escherichia coli: growth thermograms in a synthetic medium

Abstract

A microcalorimetric technique was used for studying the growth of E. coli during anaerobiosis. The growth thermograms obtained are complex and the shape of curves is dependent on the hydrogen lyase activity of the cells. Fermentation balances are given for different culture conditions, and simple growth thermograms are obtained when the hydrogen lyase activity is inhibited.
