Case 2 Aerobic Glucose + 0.18 O2 1.45 Propanediol + 0.2 H2O +1.63 CO2
Simulation Result from Copasi Conc. 1.45 Time

Simulation Result from Copasi 1.42 Conc. Time
Conclusions • Our proposed experiment resembles case1 (Anaerobic). • Case1 is not the best procedure to maximize the yeild of PDO. • The results of linear programming technique and Copasi tool are similar to biological data.
