Abstract
The present disclosure relates to a composition for screening an intestinal environment-improving material and a screening method using the composition, and according to the composition and the method of the present disclosure, it is possible to provide an effective analysis method for screening a microbiota-improving candidate material in a personalized manner by providing a method for verifying personalized probiotics, prebiotics, foods, health functional foods and drugs under in vitro conditions based on microbiota and microbiota metabolites.
Claims19
A method for screening an intestinal environment-improving material, comprising:
- (a) mixing a composition for screening an intestinal environment-improving material with a sample obtained from a subject;
- (b) treating the mixture from step (a) with one or more intestinal environment-improving candidate materials and culturing the mixture;
- and
- (c) analyzing the culture from step (b) to analyze toxin, intestinal microbiota, microbiota-derived metabolite, or a mixture thereof in the culture to determine content or concentration thereof,
- wherein
- the composition for screening an intestinal environment-improving material does not include protein and carbohydrate.
A method for screening an intestinal environment-improving material, comprising:
- (1) preparing a mixture of human or animal feces and a Pharmaceutical Meta-Analysis Screening (PMAS) medium;
- (2) Dispensing identical quantities of the feces-PMAS medium mixture into culture plates in an anaerobic chamber;
- (3) screening each candidate intestinal environment-improving material;
- (4) culturing the prepared plates under anaerobic conditions with temperature, humidity and motion similar to those of the intestinal environment to ferment and culture the respective test groups;
- and
- (5) centrifuging the culture products of step (4) to obtain supernatant;
- and
- (6) testing for the presence of toxic or undesirable substances.
