Abstract
Monod equation is often employed to express the increase in microbiology concentration. However, it is an empirical equation, and no statistical analysis on its validity has been reported. In this study, 1042 data points from 88 figures in 32 literatures are used to check the validity of Monod equation. Monod equation successfully reproduced the literature data with an average error less than 5 %. Maximum growth rate of Saccharomyces cerevisiae is compared between literatures, and it is found that the maximum growth rate largely depends on strain and medium. Temperature effect on the maximum growth rate can be expressed using the Arrhenius equation.
