Diversity of gut microbiota in mouse models induced by different diets. (a) PCoA result structure of each group. (b) Taxonomic distribution of bacterial communities of NAFLD mouse fecal samples at the phylum level. (c) Firmicutes/Bacteroidetes ratio at the phylum level. (d) LDA score of differentially abundant taxa between the NFD group and the HFD group. (e) LDA score of differentially abundant taxa between the HFD group and the FV-H group. (f) Relative abundance of g_Allobaculum, g_Faecalibaculum, g_Lactococcus, g_norank_f_Muribaculaceae, g_Ileibacterium, g_Lachnospiraceae_UCG-006, g_Desulfovibrio, and g_Ruminococcus_torques_group at the genus levels. n = 8, 10, 10; #P < 0.05 vs. the NFD group, ∗P < 0.05 vs. the HFD group.
