A simple model for diauxic growth of denitrifying bacteria.
A simple model has been formulated to simulate diauxic growth of denitrifying bacteria. It is capable of fitting the experimental results of batch growth experiments with Pseudomonas denitrificans under various conditions. It successfully predicts the observed lags when a pure culture of this bacterium switches from oxygen to nitrate as terminal electron acceptor. The model includes the effect of carbon substrate limitation and length of aerobic phase and does not run into problems when switching from anoxic to aerobic conditions, unlike prior models of diauxic growth.
