Identification
Name: Acetic acid
Description:Acetic acid is one of the simplest carboxylic acids. The acetyl group, derived from acetic acid, is fundamental to the biochemistry of virtually all forms of life. When bound to coenzyme A it forms acetyl-CoA, which is central to the metabolism of carbohydrates and fats. However, the concentration of free acetic acid in cells is kept at a low level to avoid disrupting the control of the pH of the cell contents. Acetic acid is produced and excreted by certain bacteria, notably the Acetobacter genus and Clostridium acetobutylicum. These bacteria are found universally in foodstuffs, water, and soil, and acetic acid is produced naturally as fruits and some other foods spoil. (Wikipedia) Acetic acid, or more accurately, acetate, a derivative of acetic acid, can be produced by Pseudomonas aeruginosa through fermentation in glucose metabolism. (KEGG, PMID 18600996)
