Yeast mannan increases abundance and suppresses putrefactive compound production in fecal microbiota fermentation.

Yeast mannan is a part of yeast cell wall and can potentially affect gut microflora as a soluble dietary fiber. We demonstrated that yeast mannan suppressed putrefactive production and increased the relative abundance of in fecal fermentation. These results suggest that yeast mannan can be used as a novel prebiotic food ingredient.
