Figure 2

Performance comparisons of butanol fermentations using corn- (open symbols and broken lines) and cassava-based substrates (filled symbols and solid lines). (a) pH (line) and gas production (circle). (b) ORP (line) and H2/CO2 ratio (square). (c) Acetate (square), butyrate (circle), and glucose concentrations (triangle). (d) Total butanol concentration (square), total acetone concentration (circle), and butyraldehyde concentration in broth (triangle).
