Maximum specific growth rates and average specific glucose uptake rates of Escherichia coli strains ZF43ΔgdhA, ECW1, ECW2, and ECW3.
| Strains | Maximum specific growth rate (h−1) | Specific glucose uptake ratea (mmol g DCW−1 h−1) |
|---|---|---|
| ZF43ΔgdhA | 0.693 ± 0.015 | 1.032 ± 0.018b |
| ECW1 | 0.656 ± 0.002 | 1.168 ± 0.013b |
| ECW2 | 0.565 ± 0.001 | 0.673 ± 0.033c |
| ECW3 | 0.535 ± 0.002 | 0.295 ± 0.001b |
a
The specific glucose uptake rates were calculated during the transition phase between log-growth and stational phases of three strains. The specific glucose uptake rate of ECW2 was calculated at a different time due to its much longer log-growth phase and glucose consumption time (Figure S1). It was notable that components in the 2 × YT medium also contributed to the biomass yield.
b
Calculated on the basis of 8–18 h.
c
Calculated on the basis of 20–30 h.
The results represent the means from three independent experiments.
