Effect of supplemental glucose on the production of formate (a), lactate (b), ethanol (c), acetate (d), succinate (e), propionate (f), isobutyrate (g) and butyrate (h) by the gut contents of E. eugeniae incubated under anoxic conditions. Symbols represent the mean of triplicate incubations, and error bars indicate the s.d. Arrows indicate the time point at which the samples were taken for RNA-SIP analysis. Symbols: empty circles, control (no supplemental glucose); filled squares, [13C]-glucose treatments; filled triangles, [12C]-glucose treatments.
