Physiological data from bioreactor cultivations. A) Extracellular concentrations of D-glucose, D-xylose, xylitol and ethanol. At 47 hours, 4 g/L D-glucose and 25 g/L D-xylose were added to the cultures. One insert shows the first 8 hours of cultivation, and another the hours after addition of D-glucose and D-xylose at 47 h. B) Extracellular and intracellular concentrations of D-xylonate. C) Biomass and cell viability. Arrows indicate the times when samples for microarrays were taken. The experiments were performed in triplicate; average ± standard deviation is shown.
