Biomass formation (a), glucose consumption (b), ethanol production (c), specific glucose uptake rate/ethanol productivity (d), volumetric glucose uptake rate/ethanol productivity after 7 h (e) and ethanol and biomass yield (f) of the constructed strains under growth-coupled conditions. The data presented are from triplicates and the error bars represent standard deviations. Specific and volumetric rate values are reported for the period where all strains showed exponential growth (2.5–7 h). Yields are reported for the entire period of cultivation (0–10 h)
