The bioreactor module simulates a fermentation process, accounting for the changes in substrate, cell mass, and product. A classical Michaelis-Menten kinetic scheme is utilized for the specific growth rate. The control problem consists of manipulating the dilution rate, and maximizing the product concentration.

The specific equations, and parameters, can be found in Chapter 2 of the Seborg, Edgar, Mellichamp, and Doyle textbook.
