Scheme of anaerobic glucose metabolism in E. coli. Shown are reactions involved in anaerobic glucose metabolism. Only reactions important for the study at hand are shown. Deletions present in all mutant strains are marked by red crosses. Grey arrows indicate that the respective fermentation products are absent or strongly reduced in the mutant strains. The blue arrows marks the Glc-PTS that is present in some of of the strains. The red arrow indicates the reaction catlyzed by Pck, while the green arrow indicates the reaction of the Ppc. ATP and NAD are not show in the figure with exeption of the ATP gained by Pck
