This simulation calculates steady-state values of state variables in a chemostat at different dilution rates. The results are plotted against the dilution rate (D=F/V).
The max specific growth rate was set to 0.75 h^-1 in this simulation and therefore cell concentration becomes zero above D=0.75 h^-1.
More variables (e.g. dead biomass, a non-limiting substrate concentration, and a product concentration )are calculated in the simulation, but not shown here. The file includes the option to study also the effect of biomass re-circulation.

The model permits also simulation ofthe effects of cell recirculation.
