Growth, cellobiose consumption and metabolite formation during fermentation in C. acetobutylicum under CL (dashed line) and C (solid line) conditions; a Growth/dry cell biomass (closed triangle), cellobiose consumption profiles (striked cross), b H2 production (open triangle), c acetic acid (closed square), d butyric acid (open square) and e ethanol (closed circle) and f butanol (open circle). Data were taken from four biological replicates and mean values with the error bars indicate standard error of the mean. Arrows indicate the sampling points for iTRAQ quantitative proteomic analysis (16 and 48 h). *p ≤ 0.05 and **p ≤ 0.0099
