Acetate formation and dissolved oxygen responses to feed transients in Escherichia coli fermentations: Modeling and experiments

Research output: Contribution to conferencePaper, not in proceeding

Abstract

Two hypotheses for acetate formation in <em>Escherichia coli</em> are used to obtain relations between glucose uptake, oxygen uptake and acetate production. Based on these relations, models for dissolved oxygen responses to feed rate transients are derived. Simulations of the models are compared with experimental data. It is shown that information about acetate production can be obtained from the dissolved oxygen measurement by making short pulses in the feed rate.
