  1. Bold values indicate significantly different levels of expression as determined by ANOVA. For the PM vs. WT in 0% and 10% v/v Populus hydrolysate, a positive/negative value represents a higher/lower expression level in the PM compared to the WT. For the standard medium (0%) versus Populus hydrolysate media (10 or 17.5%) positive/negative values represents higher/lower expression levels in the hydrolysate media compared to standard medium. Values are indicated for samples collected during mid-log (ML) and late-log (LL) growth phases.
