The stability conditions of the fed-batch reactor. Part II: Luedeking–Piret type growth kinetics

The performance of a cyclic reactor was examined using a kinetic model allowing for inhibition by the metabolic product of the growth of microorganisms and production coupled with their growth and maintenance. The reactor's stability field was investigated through a search for cyclically stable solutions giving Sf ≠ O and Xf ≠ O. The productivity pattern and substrate utilisation as functions of the operating variables were studied within this field. Comparison of these results with those obtained with a Monod-type kinetics leads to the conclusion that they are of general validity and do not depend on the kinetic model adopted.
