Carbohydrate fermentation is a process in which microorganisms utilize carbohydrates to produce energy.
During this process, the carbohydrates are anaerobically catabolized into organic acids, which decreases the pH of the medium and may lead to the production of gas.
Different bacteria have varying abilities to ferment specific carbohydrates, and the end products of fermentation may also vary among bacterial groups.
Plant carbohydrates, despite being composed of a limited set of monosaccharides, exhibit vast structural diversity. This diversity arises from variations in:
Additionally, the imprecision of biosynthetic enzymes contributes to significant structural variations among plant species and tissues.
In contrast, microbial Glycoside hydrolases (GHs) / Alfa-glucosidases are highly specific in their degradative activities. This specificity necessitates numerous distinct enzymes to break down complex polysaccharides, thereby limiting microbial access.
A fiber- and carbohydrate rich diet results in high fermentation and production of butyrate, enterodiol and enterolactone
Normally, bacteria in the colon help break down complex carbohydrates that the body can't digest. This process produces short-chain fatty acids, which provide 3–9% of our daily calories
Bacteroides is characterized by the ability to ferment a variety of carbohydrates and by a relatively high tolerance for oxygen
