✦ Synopsis

A mathematical model of batch acetonobutylic fermentation under glucose limitation is proposed. Making use of available information on the physiology of the process this model correctly predicts the two phases of growth and product formation observed at low extracellular pH, with production of butanol and acetone predominating in the final stage and butyrate and acetate production predominating at more neutral pH. A fair agreement between the prediction and experiments performed in different laboratories at different substrate concentrations and pH was achieved.

A mechanistic model is presented that describes the respiro-fermentative physiology of yeast. The model assumes the presence of multiple types of glucose carriers and multiple assimilation pathways. Respiro-fermentative physiology is explained by the mechanistic response of the different types of ca
