From: Xylitol enhances synthesis of propionate in the colon via cross-feeding of gut microbiota
A The quantity of enzyme before and after xylitol supplementation (Before-AC0, After-AC2). B Scatter plot of KEGG enrichment of differentially expressed genes (Rich factor: the number of differential genes located in the KEGG. The larger the rich factor is, the higher the concentration of KEGG is. Color: metabolic significance difference value). C Distribution of acyl phosphate transferase (EC 2.3.1.8), a key enzyme for propionate metabolism, in microorganisms (Before-AC0, After-AC2). D Growth curve of intestinal microorganisms in different carbon sources ((a) Escherichia coli, (b) Bifidobacterium adolescentis, (c) Bacteroides fragilis, (d) Lactobacillus reuteri, (e) Saccharomyces cerevisiae). E Growth curve of co-cultivation of double and three bacteria ((a) glucose as the carbon source in double bacterial cultivation; (b) xylitol as the carbon source in double bacterial cultivation; (c) glucose as the carbon source in three bacterial cultivation; (d) xylitol as the carbon source in three bacterial cultivation) (Before-AC0, the sample in the ascending colon before adding xylitol was defined as Before; After-AC2, the sample in the ascending colon after adding xylitol for 2 days was defined as After)
