Propionate fermentation

Propionate fermentation is a process carried out by certain microbes in the digestive system, especially in ruminants like cows. These microorganisms break down complex plant materials, producing various acids as byproducts, with propionate being one of the main types. Propionate is important because it serves as a key energy source for the animal—similar to how carbohydrates do in humans. This fermentation process helps animals efficiently convert fibrous plant material into usable energy, supporting their growth and production, such as milk or meat.
