Maximization of steady‐state Bacterial production in a chemostat with pH and substrate control

This analytical study deals with the steady‐state behavior and control of microbial growth in continuous cultures. A second order Haldane‐Monod model of continuous cultures is used as a basis for study of the effects of the adjustment of pH by the addition of acidic (or basic) materials. The treatment of a hydrogen ion concentration, in addition to substrate and microbial concentrations as state variables, results in a third order system of equations describing the process.
