Stoichiometry of macroscopic model and estimated fluxes at the end of phase III
| Flux | mol Cmolx−1 h−1 | Macroscopic process |
|---|---|---|
| qethanol | 0.081 | 1/2 Glucose → ethanol + CO2 + ATP |
| qacetate | 0.008 | 1/2 Glucose → acetate + CO2 + ATP + NADH + NADPHc |
| qglycerol | 0.009 | 1/2 Glucose + ATP + NADH → glycerol |
| qanabolisma | 0.2 Glucose + 1.65 ATP → biomass + 0.24 CO2 + 0.38 NADH | |
| qcatabolism | Glucose → 6 CO2 + 12 NADH + 2 ATP | |
| qO2b | −0.061 | O2 + 2 NADH → 2 ATP |
| qglucosed | −0.096 | |
| qCO2d | 0.157 |
a
The stoichiometry of the anabolic reaction was adapted from reference 51.
b
An effective P/O ratio of 1 was assumed, as reported previously (51).
c
For simplicity, NADPH was not balanced.
d
qglucose and qCO2 represent the sums of fluxes through all glucose-consuming and CO2-producing processes, respectively.
