Figure 5. The correlation between specific metabolites and intestinal microbiota was found by correlation thermogram analysis. Desulfovibrio had a significant positive correlation with Benzoic acid and 4-Hydroxybenzoic acid (P < 0.05). (Below is the difference metabolite, on the right is the difference species, the color depth indicates the correlation size, blue indicates the negative correlation, red indicates the positive correlation, P value is the correlation test result, in the figure, * indicates P < = 0.05, * * = P < = 0.01).
