Propionate fermentation is a form of fermentation with propionic acid as one of the products. This process is done through the fermentation pathway of bacteria. It is used in a variety of industrial, food-making, and medical applications.
Members of the genus Propionibacterium are widely used in the production of vitamin B 12, tetrapyrrole compounds, and propionic acid, as well as in the probiotics and cheese industries. [7] The strain Propionibacterium freudenreichii subsp. shermanii is used in cheesemaking to create CO 2 bubbles that become "eyes"—round holes in the cheese. [8]
Ibuprofen was derived from propionic acid by the research arm of Boots Group during the 1960s. [73] The name is derived from the 3 functional groups: isobutyl (ibu) propionic acid (pro) phenyl (fen). [74] Its discovery was the result of research during the 1950s and 1960s to find a safer alternative to aspirin.

In many cases, propionic acidemia can damage the brain, heart, kidney, liver, cause seizures and delays to normal development such as walking or talking. The accumulation of propionic acid is known to induce differential responses in different organs. The heart and liver are specific targets of the complication.
