Simulation with yeast_chemostat_ss.fig

X: Biomass concentration; G: Glucose concentration; DOT: Dissolved oxygen tension; qO: Specific oxygen consumption rate
Xf: Part of X produced by fermentative path (overflow); E Ethanol concentration; RQ: respiratory quotient

This simulation calculates steady-state values of state variables in a glucose limited chemostat with S. cerevisiae. The results are plotted against the dilution rate (D).
When D approaches 0.3 h
-1 the glucose uptake rate exceeds a critical value above which additional glucose uptake is metabolized only fermentatively. This is visualized by the maximum in qO and onset of ethanol production.
