Embodiment 1

[0035] Example 1 Isolation and Identification of Pseudo-small Chain Bifidobacterium BPW0

[0036] The separation process of pseudosmall chain bifidobacteria BPW0 provided by the invention is as follows:

[0037] 1. Collection of samples

[0038] The feces of centenarians in Hainan were collected as separate samples. Before the collection, the crowd had never taken antibiotics, had no history of taking probiotics, and had no history of gastrointestinal diseases.

[0039] 2. Isolation of strains

[0040] Dilute the collected feces samples and spread them on YCFA medium, culture anaerobically at 37°C for 24-48 hours, pick a single colony and streak culture on a new YCFA medium plate to obtain purified colonies, and then spread the single colonies On the mass spectrometer plate, the lysate and the matrix were added and dried on the MALDI-TOF MS 1000 mass spectrometer (Autobio, Zhengzhou Antu Biotechnology Co., Ltd.) for identification on the machine. The identification results are...

Embodiment 2

[0042] Example 2 Preparation of Pseudosmall Chain Bifidobacterium BPW0 Live Bacteria Liquid, Metabolites and Inactivated Bacteria

[0043] 1. Culture of bacteria

[0044] Take -80°C frozen bacteria liquid and spread it on the YCFA solid plate, and after inverting culture at 37°C for 24-48 hours, take a single colony and inoculate it in the liquid YCFA medium, and cultivate it at 37°C for 18-24 hours to obtain the first-generation bacterial liquid; Take 10% of the first-generation bacterial solution and inoculate it into fresh YCFA liquid medium, incubate at 37°C for 18-24 hours to obtain the second-generation bacterial solution; take 10% of the second-generation bacterial solution and inoculate it into fresh YCFA liquid medium, and incubate at 37°C for 18-24 hours to obtain working bacteria.

[0045] 2. Obtaining live bacteria solution

[0046] The live bacterial liquid can also be obtained by other methods in the technical field, as long as the bacterial cells can be enrich...

Embodiment 3

[0052] Example 3 HepG2 cell experiment

[0053] The human-derived liver cancer HepG2 cells used in the present invention are purchased from the National Biomedical Experimental Cell Resource Bank, and the culture method is a conventional culture method used in the field. In one embodiment of the invention, the culture method is: at 37°C and 5% CO 2 Under conditions, culture in high-glucose DMEM medium containing 10% fetal bovine serum (FBS), add double antibodies (100ug / ml penicillin and 100ug / ml streptomycin) in the medium at a ratio of 1:100, every 1-2d Replace with fresh culture medium once.

[0054] The present application acts on the lipid accumulation model constructed by HepG2 cells with the bacterial strain provided by the present invention, and observes the influence of the bacterial strain provided by the present invention on lipid metabolism, specifically as follows:

[0055] 1. Oil red O staining test

[0056] HepG2 cells in logarithmic growth phase in good grow...

Abstract

The present invention provides a strain of pseudo small chain bifidobacteria ( Bifidobacterium pseudocatenulatum ) and its application in metabolic syndrome, involving the field of microorganisms, its preservation number is CGMCC No.22185, and it was preserved in the General Microbiology Center of China Committee for the Collection of Microorganisms on April 14, 2021, and the preservation address is Chaoyang District, Beijing No. 3 Institute of Microbiology, Chinese Academy of Sciences, No. 1 Yard, Beichen West Road, the pseudo-small chain Bifidobacterium provided by the invention ( Bifidobacterium pseudocatenulatum ) can significantly inhibit lipid accumulation in liver cells, reduce body weight and blood lipid levels, and then improve hepatic steatosis, which has important application significance for alleviating the occurrence of hyperlipidemia, obesity and fatty liver.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a pseudo-small chain bifidobacterium and its application in metabolic syndrome. Background technique [0002] Dyslipidemia is an important risk factor for cardiovascular and cerebrovascular diseases. Like many chronic disease risk factors such as hypertension and diabetes, it can lead to coronary heart disease, myocardial infarction, stroke and other cardiovascular and cerebrovascular diseases. Therefore, blood lipid management is currently the focus of prevention and control of cardiovascular and cerebrovascular diseases in our country. With the improvement of people's living standards, changes in diet structure, accelerated pace of life, and increased pressure, the problem of "three highs" has gradually become serious. The prevalence of dyslipidemia alone is as high as 40.4%. According to statistics from the National Center for Cardiovascular Diseases, the number of people with d...
