Figure 1. Carbohydrate utilization by the synthetic human gut microbiota (SM) members and gnotobiotic mouse treatments.
(A) Heat map showing normalized growth values of 13/14 SM members.
(B) Schematic of the gnotobiotic mouse model illustrating the timeline of colonization, feeding strategies and fecal sampling.
(C) Compositions of the three distinct diets employed in this study (common additives such as vitamins and minerals are not shown). The prebiotic mix contained equal proportions of 14 host indigestible polysaccharides (see Table S1). See also Fig. S1.
