Fermentation growth and metabolite production. Cellobiose utilization, biomass production, pH change, and metabolite production plots of C. thermocellum grown in 1191 medium batch cultures on 2 g l^-1 cellobiose. Arrows indicate sampling points for exponential and stationary phase proteomic analysis. Biomass (blue circle), cellobiose (red circle), pH (olive green diamond), H₂ (blue square), CO₂ (red square), acetate (purple triangle), ethanol (olive green triangle), formate (tan diamond).
