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 ...

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.
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes.
A vitamin B 12 –dependent enzyme catalyzes rearrangement of L-methylmalonyl-CoA to succinyl-CoA, which is an intermediate of the citric acid cycle and can be readily incorporated there. Children were challenged with calcium propionate or placebo through daily bread in a double-blind placebo-controlled crossover trial.
Certain bacteria form close spatial associations that are essential for their survival. One such mutualistic association, called interspecies hydrogen transfer, occurs between clusters of anaerobic bacteria that consume organic acids, such as butyric acid or propionic acid, and produce hydrogen, and methanogenic archaea that consume hydrogen.
