Transcriptional fold changes of xylT, xylA, and xylB of strain 824glcG-TBA compared to stain 824glcG-P
Gene | Transcriptional level (mean fold change ± SD)a |
|
---|---|---|
Acidogenic phase | Solventogenic phase | |
xylT | 1.17 ± 0.08 | 6.60 ± 0.56 |
xylA | 132 ± 27 | 30 ± 3 |
xylB | 119 ± 5 | 62 ± 4 |
The OD600 values for samples taken in acidogenic and solventogenic phases were 3.8 and 7.0, respectively. Fermentations were performed in P2 medium containing 40 g of glucose and 20 g of xylose/liter.
