Microbial Fermentation

Meaning

Microbial Fermentation is an anaerobic metabolic process carried out by bacteria, yeast, and other microorganisms, in which organic compounds, typically carbohydrates, are converted into acids, gases, or alcohol. In the context of human health, this process predominantly occurs in the gut microbiome, where commensal bacteria ferment non-digestible dietary fibers to produce beneficial short-chain fatty acids (SCFAs). This biological activity is fundamental to gut health, nutrient absorption, and the production of metabolites that influence systemic inflammation and hormonal signaling. It is a vital process that links diet to host physiology.
