The esters of propionic acid have fruit-like odors and are sometimes used as solvents or artificial flavorings. [15] In biogas plants, propionic acid is a common intermediate product, which is formed by fermentation with propionic acid bacteria. Its degradation in anaerobic environments (e.g. biogas plants) requires the activity of complex ...

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]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
These multiply, consuming the body's carbohydrates, lipids and proteins, to produce a variety of substances including propionic acid, lactic acid, methane, hydrogen sulfide and ammonia. The process of microbial proliferation within a body is referred to as putrefaction and leads to the second stage of decomposition known as bloat. [14]
p-Toluenesulfonic acid is a comparatively strong acid used in organic chemistry often because it is able to dissolve in the organic reaction solvent. Exceptions to these solubility characteristics exist in the presence of other substituents that affect the polarity of the compound.
