Enzymatic-modified dietary fibre fraction extracted from potato residue regulates the gut microbiotas and production of short-chain fatty acids of C57BL/6 mice

Potato residue is a rich source of dietary fibre. Herein, the effects unmodified and enzymes (cellulase xylanase) modified potato fibres on distribution intestinal microbiotas production short-chain fatty acids (SCFAs) C57BL/6 mice were evaluated. Results showed that enzymatic modification increased soluble fibre content in residue. Administration these promoted acetic acid, n-butyric iso-butyric valeric iso-valeric while inhibiting propionic acid (p < 0.05). The improved richness diversity microflora mice, particularly Bacteroidetes to Firmicutes ratio Modification by cellulase xylanase significantly regulating bioactivities towards gut microbiota values food applications fibres. These have potential act as therapeutic agents treat dysbiosis microbiota.
