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 ]
Short-chain fatty acids (SCFAs) are fatty acids of two to six carbon atoms. [1] The SCFAs' lower limit is interpreted differently, either with one, two, three or four carbon atoms. [ citation needed ] Derived from intestinal microbial fermentation of indigestible foods, SCFAs in human gut are acetic, propionic and butyric acid.
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.
[1] [2] Resistant starch occurs naturally in foods, but it can also be added as part of dried raw foods, or used as an additive in manufactured foods. [ 3 ] Some types of resistant starch (RS1, RS2 and RS3) are fermented by the large intestinal microbiota , conferring benefits to human health through the production of short-chain fatty acids ...

These bacteria are among the most abundant taxa in the rumen [12] and the human gut microbiota. [3] [13] [14] [15] Members of this family may protect against colon cancer in humans by producing butyric acid. [16] [17] Lachnospiraceae have been found to contribute to diabetes in genetically susceptible (ob/ob) germ-free mice. [18]

The bacterium is a gram-negative bacteria, as first classified to the Fusobacterium, however it stains as a gram-positive bacteria. [8] This can be alluded to the fact that it lacks lipopolysaccharides on its outer membrane, so it stains more closely to gram-positive bacteria, than to gram-negative.
