Figure 8

Hydrolysate fermentation kinetics. These represent fermentation of hydrolysates of alkali pre-extracted, alkaline hydrogen peroxide (AHP) post-treated corn stover by Saccharomyces cerevisiae strains metabolically engineered for xylose fermentation using either the xylose reductase (XR) + xyitol dehydrogenase (XDH) pathway (strain Y73) or the xylose isomerase (XI) pathway (strain Y128). Conditions include (A) Y73 in low-sugar hydrolysate, (B) Y128 in low-sugar hydrolysate, (C) Y73 in high-sugar hydrolysate, (D) Y128 in high-sugar hydrolysate.
