Fig. 6: Effect of AF on human gut microbiota cultured diversity.

A Alpha diversity indices (Shannon and Chao1) calculated from the raw taxonomic tables after 48 h of treatment with AF (3, 30 or 300 µg mL−1) or Van (500 µg mL−1). Kruskal–Wallis tests with Dunn’s test post hoc (Benjamini–Hochberg p value correction method) were used to compare the groups. * indicates p value < 0.05. B Spearman’s correlation of the dose of AF and Alpha-diversity indices.
