This article presents a mathematical model for biomass, limiting substrate, and dissolved oxygen concentrations during stable operation of self‐cycling fermentation (SCF). Laboratory experiments using the bacterium Acinetobacter calcoaceticus RAG‐1 and ethanol as the limiting substrate were performed to validate the model. A computer simulation developed from the model successfully matched experimental SCF intracycle trends and end‐of‐cycle results and, most importantly, settled into an unimposed periodicity characteristic of stable SCF operation. © 1995 John Wiley & Sons, Inc.
