Figure 1.

Comparison of the growth, sugar consumption and production of solvents (butanol and acetone) and butyrate between the 824ccpA (Square) and 824WT (triangle) strains when fermentingD-glucose andD-xylose with pH control. pH value was kept over 5.0 by using 9% (w/v) aqueous ammonia. Samples (indicated by arrows) for microarray analysis were collected in four time points: middle (M) and late (L)-exponential growth phase; transition phase (T) and stationary phase (S).
