Comparison of XI and XR/XDH pathway fermentation performance.

Xylose fermentations using strain SR8u (XR/XDH pathway) and strain SXA-R2P-E (XI pathway) with (A) different starting cell loadings (5-20 OD600), (B) mid-log phase cultures as fermentation seeds. The strain and starting OD600 values are indicated above each panel. The medium used in these fermentations was oMM. Error bars represent the standard deviation of biological triplicates. Xylose fermentation samples were resolved as previously described [13].
