Carbon recovery of fermentation products for engineered strains during the oxygen-limited growth on glucose
| Strain | Pyruvate | Succinate | Ethanol | Lactate | Acetate | Butyrate | Butanol | Total (%) |
|---|---|---|---|---|---|---|---|---|
| BuT-8 | 20.7 | 3.5 | 7.8 | 2.7 | 1.5 | 4.1 | 21.9 | 62.2 |
| BuT-9 | 2.6 | 2.1 | 5.2 | 1.8 | 1.2 | 2.7 | 34.8 | 50.4 |
| BuT-10 | 0.01 | 1.1 | 5.2 | 1.5 | 0.8 | 2.0 | 39.6 | 50.2 |
| BuT-12 | Nil | 0.8 | 5.2 | 1.4 | 0.7 | 1.4 | 43.7 | 53.2 |
| BuT-14 | Nil | 0.6 | 2.6 | 1.3 | 0.5 | 1.4 | 49.4 | 55.8 |
Carbon recovery was calculated as the molar percent of carbon in products per carbon in consumed glucose. Nil, carbon recovery less than 0.01
