About

The correlation between diet and microbiota as well as the effect of microbiota on human health is well established. Studies have shown that people following specific diets have different microbiome profile compared to those following traditional or ordinary diets. In order to screen several food ingredients for their effects on human microbiota composition and metabolic activities, in vitro studies are proposed. Nutrients are added in-vitro in fecal sample, eliminating the need for participants to consume any nutritional product. The batch fermentation in vitro system simulates human colonic microbiota from fecal samples, enabling the complex mixture of microorganisms. This system could serve as a simple model to simulate the diversity as well as the metabolism of human colonic microbiota. We will evaluate the effect on nutrient/s on the age specific microbiome via an in vitro fermentation approach for the 0 to 60 year-old period.
