P. pentosaceus CECT 8330 modulates the gut microbiota diversity. A Alpha diversity index (observed species, Chao, Ace and Simpson) of the fecal microbiome in the Control, DSS and DSS + CECT 8330 groups at the OTU level. B Beta diversity of bacterial using Principal Coordinate analysis (PCoA) based on Bray–Curtis distance between the three groups at the phylum, genus, and OTU level. Significance was determined by Kruskal–Wallis test or ANOVA with Tukey’s analysis. *P < 0.05, **P < 0.01
