FIG. 3.

Physiological parameters during anaerobic growth on 50 g of glucose per liter and 50 g of xylose per liter for TMB3001, the 460-generation population, and 15 clones isolated from this population. (A) Maximum growth rate and biomass yield during exponential growth on glucose. (B) Specific xylose uptake rate and xylitol yield on xylose between the time that glucose was depleted and 100 h of fermentation. (C) Final ethanol concentration at 180 h. Values for TMB3001 and the populations are averages from duplicate experiments. The horizontal lines indicate the reference values for TMB3001.
