Figure 4From: Altering the coenzyme preference of xylose reductase to favor utilization of NADH enhances ethanol yield from xylose in a metabolically engineered strain of Saccharomyces cerevisiaeXylose utilization and product formation during anaerobic bioreactor cultivation of BP000 (panel A) and BP10001 (panel B). Xylose (full squares), ethanol (triangles), xylitol (circles), glycerol (stars) and acetate (empty squares) were analyzed by HPLC. The biomass concentration was constant at 1.6 ± 0.1 g/L for BP000 and 1.8 ± 0.1 g/L for BP10001.Back to article page
