Fig. 3From: Examination of hydrogen cross-feeders using a colonic microbiota modelSCFA concentrations in the three fermenter compartments over the course of the 42-day experiment of Payne et al. [14]. This figure pertains to the experiment with faecal material from the obese child, run in batch mode with high-energy (HE) medium for 2Â days, then switched to continuous fermentation. During continuous fermentation, the model was run in four 10-day periods with differing media, in the following order: HE, normal-energy (NE), HE, low-energy (LE). Measured data are indicated with coloured circles, solid lines indicate the model prediction using the Alpha parameter set, and dashed lines indicate the prediction using the Beta parameter set. The dotted vertical lines indicate changes between mediaBack to article page
