Butyrate fermentation is a process that produces butyric acid via anaerobic bacteria. This process occurs commonly in clostridia which can be isolated from many anaerobic environments such as mud, fermented foods , and intestinal tracts or feces. [ 1 ]
Butyric acid is used in the preparation of various butyrate esters. It is used to produce cellulose acetate butyrate (CAB), which is used in a wide variety of tools, paints, and coatings, and is more resistant to degradation than cellulose acetate. [30] CAB can degrade with exposure to heat and moisture, releasing butyric acid. [31]

Studies show that F. prausnitzii interacts with other bacteria, which affects its butyrate production, and survival. When F. prausnitzii is cultured with Bacteroides thetaiotaomicron, it produces more butyric acid than standing alone, [26] [12] F. prausnitzii also benefits from growing with certain other bacteria. For example, in order to ...
Clostridium butyricum is a strictly anaerobic endospore-forming Gram-positive butyric acid–producing bacillus subsisting by means of fermentation using an intracellularly accumulated amylopectin-like α-polyglucan (granulose) as a substrate.
The ABE fermentation pathway generally proceeds in two phases. In the initial acidogenesis phase, the cells grow exponentially and accumulate acetate and butyrate. The low pH along with other factors then trigger a metabolic shift to the solventogenesis phase, in which acetate and butyrate are used to produce the solvents. [4]
Butyrate is an energy source for colon cells. butyrate-yielding diets thus decrease gut permeability by providing sufficient energy for the formation of tight junctions. [156] Additionally, butyrate has also been shown to decrease insulin resistance, suggesting gut communities low in butyrate-producing microbes may increase chances of acquiring ...
Halophilic bacteria can produce bioplastics in hypersaline conditions. Solid-state fermentation adds a small amount of water to a solid substrate; it is widely used in the food industry to produce flavors, enzymes and organic acids. [29]
