Fig. 7From: Age-related changes of microbiota in midlife associated with reduced saccharolytic potential: an in vitro studyThe correlation of metabolites and fermented microbiota composition. Spearman’s correlation coefficient analysis was performed to reveal the relationship between the metabolites and fermented microbiota of starch (a) and inulin (b). The calculated coefficients are shown in heatmap. Ac: acetate, Pr: propionate, Bu: butyrate, iBu: isobutyrate, Va: valerate, iVa: isovalerate, +: p < 0.05, *: p < 0.01Back to article page
