FIGURE 3.

Comparison of amino acid consumptions and related metabolites (branched chain fatty acids and H₂S) from three independent chemostat experiments of fecal culture at dilution rate 0.05 (blue dots) and 0.2 (red dots) 1/h in apple pectin medium. Positive values indicate the production and negative values indicate the consumption of the amino acid. Numbers behind the metabolite name indicate significant difference between D_low and D_high (D = 0.05 and 0.2 1/h, respectively). isoval, isovalerate; isobut, isobutyrate.
