Effect of diet intervention on the gut microbiota. (A) The amount of OTU based on 97.0% similarity. (B) Shannon index. (C) The change in the phylum level. (D) The change in the genus level. (E) The relative abundance of Lachnospiraceae_NK4A136- group. (F) The relative abundance of Lactobacillus. (G) The relative abundance of Enterococcus. (H) The relative abundance of Streptococcus. (I) LDA score of four diets on microbiota. Data are presented as mean ± SEM. Different letters indicate statistical differences among the groups (p < 0.05). OTU, operational taxonomic unit; CTG, control group; LPG, low protein group; CG, casein group; SPG, soy protein group.
