Fig. 4: R. bromii was inhibited by BBR to attenuate DCA transformation.

a The two-panel heatmap on the left shows the correlations between the key BBR responsive species and with major clinical outcomes and plasma levels of bile acid. The colour key shows Rho calculated by partial Spearman’s correlation with adjustment for age, sex and BMI. Δ of clinical parameters or BAs = 100% × (baseline value − post treatment value)/baseline value. Species in blue represent depleted species and species in orange represent enriched species after BBR treatments. *P < 0.05. b Bile acid transformation assay for R. bromii. The percentage composition of deoxycholic acid (DCA) and lithocholic acid (LCA) in the culture media with which R.bromii had grown for 24 h with primary bile acid (CA and CDCA) treatment were measured by LC/MS. n = 3, data are shown as the mean ± SD. c The growth curve of R. bromii with different concentrations of BBR in the in vitro culture experiment, demonstrated a significant inhibitory effect of BBR on R. bromii starting at a concentration of 25 μg ml−1, n = 3, P < 0.001, determined by two-way repeated-measures ANOVA, data are shown as the mean ± SD. Bifidobacterium catenulatum − Bpc, B. catenulatum–Bifidobacterium pseudocatenulatum complex. Source data and exact P-value are provided in the Source Data file.
