Principal coordinates analysis (PCoA) of weighted UniFrac distances. Between community diversity among stool samples was tested for the impact of β-glucan amount and MW on the clustering patterns of microbiota in (A) 5 g LMW vs. 3 g HMW (P = 0.35), (B) 3 g LMW vs. 3 g HMW (P = 0.13), (C) 3 g LMW vs. 3 g HMW (P = 0.014), (D) 3 g LMW vs. Control (P = 0.53), (E) 3 g HMW vs. Control (P = 0.011), (F) 5 g LMW vs. Control (P = 0.044). Symbols with different colors represent samples belonging to individuals under specific treatment. For each comparison, the P-value was obtained from PERMANOVA and considered significant for P < 0.05.
