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. It is uncommonly reported as a human pathogen and is widely used as a probiotic in Japan, Korea, and ...

Sodium butyrate is a compound with formula Na(C 3 H 7 COO). It is the sodium salt of butyric acid.It has various effects on cultured mammalian cells including inhibition of proliferation, induction of differentiation and induction or repression of gene expression. [1]
The word "butyl" is derived from butyric acid, a four-carbon carboxylic acid found in rancid butter. [1] The name "butyric acid" comes from Latin butyrum , butter . Subsequent preferred IUPAC names for alkyl radicals in the series are simply named from the Greek number that indicates the number of carbon atoms in the group: pentyl , hexyl ...
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]
Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound.Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation.
