Ethanol profile for ER and ISO12 obtained in small vials with 100% hydrolysate at 39°C. The profiles of in vivo conversion of furfural and HMF (shown as disappearance of the compounds) are also included. Initial biomass was about 1 g/l cdw. Cells were pre-grown on YPD at 30°C. The values are the average of at least two independent experiments. The bars represent the deviation from the average.
