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 ]
In particular, butyrate inhibits colonic tumor cells and stimulates proliferation of healthy colonic epithelial cells. [ 70 ] [ 71 ] The explanation why butyrate is an energy source for normal colonocytes and induces apoptosis in colon cancer cells, is the Warburg effect in cancer cells, which leads to butyrate not being properly metabolized.
Acetate, propionate and butyrate are the three most common SCFAs. [3] Butyrate is particularly important for colon health because it is the primary energy source for colonocytes (the epithelial cells of the colon). [1] [2] The liver can use acetate for energy. [5]
The fermentation of resistant starch produces short-chain fatty acids, including acetate, propionate, and butyrate and increased bacterial cell mass. The short-chain fatty acids are produced in the large intestine where they are rapidly absorbed from the colon, then are metabolized in colonic epithelial cells, liver or other tissues.
Formerly considered to be a member of Fusobacterium, the bacterium is named in honor of German bacteriologist Otto Prausnitz.In 2002, it was proposed to be reclassified as its own genus, Faecalibacterium, containing the species Faecalibacterium prausnitzii, as phylogenetic analysis from isolates showed it to be only distantly related to Fusobacterium, and a closer member of Clostridium cluster ...

Quorum sensing among cells is the process among which cell signaling can lead to coordinated activities which can ultimately help bacteria control gene expression in a consecutive sequence. This is accomplished via detection of small autoinducers which are secreted in response to increasing cell-population density. [ 13 ]
