Effect of Functional Oligosaccharides and Ordinary Dietary Fiber on Intestinal Microbiota Diversity

摘要

FIGURE 1. Effects of the three treatments on the composition of fecal microbiota. (A) Experimental design. (B) A plot of the Shannon–Wienner diversity and Chao index at 4-week point. (C) Relative abundance of the main genera at 4-week point. (D) Analysis of taxonomic abundances using LEfSe indicates that multiple taxa are differentially enriched in the feces of four groups. (E) A PCoA analysis of the UniFrac distance in the feces of four groups. GI, galacto-oligosaccharides + inulin group; PF, polydextrose + insoluble dietary fiber group; GIPF, GI and PF supplementation at a 1:1 ratio group. “0” indicates the first week. “1” indicates the third week. “2” indicates the fourth week.
