Figure 9

Determination of ethanol yields in strains Y73 and Y128. Plotting xylose consumption versus ethanol production for both corn stover hydrolysates (Table 1 and Figure 7) for strains Y73 and Y128 results in the regression of the slope that represents the average ethanol yield on xylose, Y EtOH/Xyl , (g/g). The average ethanol yield on xylose in the strain utilizing the xylose isomerase pathway (Y128) was slightly higher than that of the strain utilizing the reductase/xylitol dehydrogenase pathway (Y73).
