propionic acid

[pro″pe-on´ik]

a fatty acid found in chyme and sweat, and one of the products of bacterial fermentation of wood pulp waste; its salts (calcium propionate and sodium propionate) are antifungal agents and inhibitors of mold on foods.

Effect of Glucose and Lactic Acid Bacteria on the Fermentation Quality, Chemical Compositions and in vitro Digestibility of Mulberry (Morus Alba) Leaf Silage

Currently, almost all propionic acid is produced by the chemical synthesis of raw materials derived from petroleum (Tufvesson, Ekman, Sardari, Engdahl, & Tufvesson, 2013).

It is revealed that the comparatively lower concentration of 80% of formic acid was required than that of acetic and propionic acid. As the quality of the delignified product, propionic acid would give better end product in higher yield as compared to the lower aliphatic acid that was observed.

In this study, propionic acid and PmB were significantly associated with IBS, and PmB was negatively associated with IL-10 in the CSF, which may suggest that the SCFA are involved in the brain-gut communication.

Joint feeding of the studied biologically active preparations not only increased the intensity of the fermentation processes in the rumen but also changed their focus toward increased propionic acid fermentation, which is evidenced by higher propionic acid value in the total VFA content in the rumen of bull-calves in the third experimental group by 5.8% in absolute units (P > 0.95), as compared to the reference group.
