Figure 5. Biodiesel produced by an engineered E. coli strain fed hydrolysates derived from JTherm or CTec2 hydrolysis of IL-pretreated switchgrass.

(A), and percentage of glucose remaining after fermentation (B). Glucose levels were adjusted to 2% for all hydrolysates and controls. The JTherm and CTec2 controls contained purified glucose and xylose at the same levels as their corresponding hydrolysate. No xylose was consumed during the fermentation (data not shown). Error bars indicate the standard deviation of triplicate experiments.
