Evaluation of the stability of D-xylose fermentation capacity in strain GS1.11-26. (a) Comparison of the number of colonies growing in YPD and YPX after growth for about 50 generations in non-selective conditions with only glucose as carbon source. Error bars represent standard deviation from three independent experiments. (b) Fermentation performance in YP + 40 g/L D-xylose as estimated from weight loss due to CO2 release. Colonies 1 to 10 represent randomly selected single-cell clones isolated after growth of GS1.11-26 for 50 generations in YPD medium. The parent strain HDY.GUF5 is shown for comparison.
