Numerous gut microbes such as Bacteroides, Bifidobacterium, Ruminococcus, and Roseburia spp, Clostridium, Eubacterium, and Enterococcus genera will help in the anaerobic degradation of the undigested dietary polysaccharides (fermentation process)
The major end products of polysaccharide fermentation are SCFA
acetate, propionate, and butyrate, which provide energy for the host and are involved in the physiological functions.
