Figure 3. Microbiota composition observed during fecal batch in vitro fermentations using a donor low in Bifidobacterium spp.. Mean relative abundance (%) of common genera (at least 1% relative abundance and 50% prevalence in all samples) detected in in vitro fermentations over time (t = 0, 6, 24 and 48 h in the control (Control; only inoculum) and for inulin (Inulin) vs. dried chicory root powder (Powder) or cubes (Cubes). The lower panel zooms in on the common taxa, omitting the contribution of Escherichia-Shigella spp., which dominated the community between 0 and 6 h of fermentation.
