Effect of the HXBM408 bacteria on rat intestinal bacterial diversity and the metabolism of soybean isoflavones.

ABSTRACT: The purpose of this study was to investigate the effect of the HXBM408 bacteria on the diversity of rat intestinal bacteria and the metabolism of soybean isoflavones. The control group was administered sterilized water and daidzein by gavage for 7 days. Conversely, the experimental group was administered HXBM408 solution and daidzein by gavage for 7 days. The content of the daidzein metabolite equol in rat feces in the experimental group was significantly higher than that in the control group (P < 0.05) on the 7th and 14th days. However, the content of daidzein and its metabolites in feces was not significantly different (P > 0.05). On the 7th day, the relative abundance of Streptococcus in the feces of the experimental group was significantly higher than that of the control group (P < 0.05), but the difference disappeared over time (P > 0.05). In the intestinal digesta of rats, the proteobacteria of the experimental group was significantly lower than those of the control group (P < 0.05). HXBM408 can increase the degradation ability of soybean isoflavones in a short period after ingestion, increase the number of beneficial intestinal flora, and improve the structure of the flora.
