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 ...

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.
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]
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.

Propionyl-CoA is a coenzyme A derivative of propionic acid.It is composed of a 24 total carbon chain (without the coenzyme, it is a 3 carbon structure) and its production and metabolic fate depend on which organism it is present in. [1] Several different pathways can lead to its production, such as through the catabolism of specific amino acids or the oxidation of odd-chain fatty acids. [2]
