Embodiment 1

[0032] Take a 250ml Erlenmeyer flask, add 200mL of pure water, then add 0.72g of glucose, 2.4g of soybean peptone, 0.6g of threonine, 0.88g of N-acetylglucosamine, 0.9g of sodium chloride and 0.4g of dihydrogen phosphate Sodium, after fully stirring and mixing, the medium is autoclaved, and after the medium is cooled, inoculate 100 μL of Akkermansia muciniphila bacteria liquid into the medium (Akkermans muciniphila in the bacterial liquid The bacteria content is 2.6×10 8 cfu / mL) and 200 μL cysteine, placed in an anaerobic box (85% CO 2 ,10%N2 and 5%H 2 ) (cultivation temperature is 37°C) after 3 days, take it out, centrifuge at 3000rpm for 10min, observe the amount of precipitated bacteria, resuspend the precipitate with 5mL of sterile PBS, and use NanoDrop to measure the OD of the bacterial solution 600 value, OD 600 The value is 0.0183.

Abstract

The invention provides a culture medium for culturing akkermansia muciniphila and a use method thereof, and belongs to the technical field of microorganism culture mediums. Components of the culture medium include soy peptone, threonine, glucose, N-acetylglucosamine, sodium chloride and disodium hydrogen phosphate. By adopting the culture medium, the akkermansia muciniphila quantity required by functional studying of the akkermansia muciniphila can be reached through culture, the components of the culture medium have safe sources, and potential biological hazards do not exist.

Description

technical field [0001] The invention belongs to the technical field of microbial culture medium, and in particular relates to a culture medium for cultivating Akkermansia muciniphila and a use method thereof. Background technique [0002] Obesity and its associated metabolic diseases such as diabetes and cardiovascular disease have become a major threat to public health. The situation in my country is particularly severe. There are more than 100 million diabetic patients, and nearly 500 million people are pre-diabetic. Therefore, it is particularly important to study measures to prevent and treat such diseases. [0003] Gut flora is closely related to human health. Obesity and insulin resistance are two important early features of metabolic diseases, and gut flora plays an important role in the occurrence and progression of metabolic diseases. Altered gut microbiota, inflammation, and disrupted gut barrier function are important features of obesity and type 2 diabetes. Ex...
