Propionic acid inhibits the growth of mold and some bacteria at levels between 0.1 and 1% by weight. As a result, some propionic acid produced is consumed as a preservative for both animal feed and food for human consumption. For animal feed, it is used either directly or as its ammonium salt. This application accounts for about half of the ...

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]
Propionibacterium freudenreichii was first discovered and isolated in the early 20th century by Eduard von Freudenreich and Sigurd Orla-Jensen. They discovered the bacterium while studying propionic acid fermentation in Emmental cheese.

These bacteria produce carbon dioxide and a number of compounds that account for the unique odor: pungent (propionic acid), rotten-egg (hydrogen sulfide), rancid-butter (butyric acid), and vinegary (acetic acid). [8] Due to these gases, a thousand cans of surströmming exploded over a period of six hours during a fire at a Swedish warehouse in ...
