Abstract: Provided is a strain CCFM8631 of Lactobacillus reuteri and use thereof. The strain CCFM8631 of Lactobacillus reuteri can significantly increase neurotransmitter 5-hydroxytryptamine level in peripheral blood, recover the hormone levels, for example testosterone and so on in peripheral blood of rat, normalize abnormal abundances of Blautia genus and Turicibacter genus, Oscillospira genus and Bifidobacterium genus in intestinal flora of rat affected by high-fat high-starch diet, show good tolerance to simulated gastrointestinal fluid and quickly colonize in intestinal, significantly improve pathological damages of tissues such as liver, duodenum and so on, and increase triglyceride and total cholesterol levels in serum and oral glucose tolerance of rat with metabolic syndrome caused by high-fat high-starch diet.

Abstract: Provided is a strain CCFM8630 of Bifidobacterium adolescentis and use thereof. The strain CCFM8630 of Bifidobacterium adolescentis can significantly increase neurotransmitter 5-hydroxytryptamine level in peripheral blood of rat, recover the hormone levels, for example testosterone and so on in peripheral blood of rat, normalize abnormal abundances of Bifidobacterium genus, Blautia genus and Turicibacter genus in intestinal flora of rat affected by high-fat high-starch diet, show pretty good tolerance to simulated gastrointestinal fluid and quickly colonize in intestinal, significantly improve pathological damages of tissues such as liver, duodenum and so on, and increase triglyceride and total cholesterol levels in serum and oral glucose tolerance of rat with metabolic syndrome caused by high-fat high-starch diet.
