Abstract
The general model proposed by Ratkowsky et al. (J. Bacteriol. 154, 1222–1226, 1983) to describe the variation of bacterial growth rate with temperature was tested using data for growth of Escherichia coli in a variety of media. In two of nine cases the data fitted well to the proposed model and in one case deviations from the model were minor, but in the remaining six cases the data at the upper and/or lower end of the temperature range deviated markedly from the model. However, the relationship between the square root of growth rate and temperature that is exploited in the general model appears to offer a suitable basis for specific models describing the temperature dependence of bacterial growth in particular media.
