Fig. 3From: Age-related changes of microbiota in midlife associated with reduced saccharolytic potential: an in vitro studyThe impact of age and culture medium on microbiota. CCA was used to show the variation in microbiota composition affected by the age groups and the sole carbon hydrates. The samples from midlife (blue) and young (red) group were plotted. The starch fermentation samples were clustered by solid line and inulin fermented samples were clustered by dotted lineBack to article page
