Proteolytic Fermentation
Proteolytic fermentation occurs when protein is broken down by
gut bacteria [35]. While normal in small amounts, excessive
proteolytic fermentation can produce problematic byproducts:
● Ammonia [36]
● Phenols [37]
● Sulfides [38]
● Various amines [39]
These byproducts can be inflammatory and potentially toxic when
produced in excess [40]. High proteolytic fermentation may
indicate:
● Excessive protein consumption [41]
● Poor protein digestion in the upper GI tract [42]
● Dysbiotic shifts in microbial populations [43]
● Insufficient fiber intake to support saccharolytic fermentation
[44]
Gas Production Patterns
Microbial gas production provides additional insights into
functional patterns:
Methane Production
Methane-producing organisms (methanogens) can significantly
impact gut function by:
● Slowing intestinal transit time [45]
● Potentially contributing to constipation [46]
● Competing with beneficial acetate producers [47]
