Butyric acid is a carboxylic acid compound. Butyric acid is an important C4 organic acid with broad applications.
Butyric acid ; Appearance, Colorless liquid ; Odor, Unpleasant, similar to vomit or body odor ; Density, 1.135 g/cm3 (−43 °C) · 0.9528 g/cm3 (25 °C)
Butyric Acid is currently produced by chemosynthesis from petroleum-based feedstocks. However, the fermentative production of butyric acid from renewable feedstocks has received growing attention because of consumer demand for green products and natural ingredients in foods, pharmaceuticals, animal feed supplements, and cosmetics.
In this review, strategies for improving microbial butyric acid production, including strain engineering and novel fermentation process development are discussed and compared regarding product yield, titer, purity and productivity. Future perspectives on strain and process improvements for butyric acid production are also discussed.
