FIG. 1.

End products and biomass production from glucose by strain VeGlc2. The fermentation end products from glucose were acetate (▵), propionate (▴), and succinate (□). Also shown are the final pH of the growth medium (○), the ratio of propionate plus succinate to acetate (■), and the amount of biomass produced, as measured by optical density at 650 nm (OD₆₅₀) (•), after growth on different amounts of glucose. The mean carbon and available H balances of the experiments were 97.3 and 97.6%, respectively.
