Occurrence. In the second step, ethyl alcohol is further oxidized to form acetic acid using acetobacter bacteria. Fermentation is a pretty commonly used term in the alcohol industry, and although the overarching concept is relatively simple to grasp, many imbibers aren’t fully aware of the intricacies of this essential booze-creating process. Various alcoholic beverages, for example, beer, wine are produced from the fermentation of yeast and sugar such as grapes, rice, grain, and berries. Wine is produced by fermentation of the natural sugars present in grapes and other kinds of fruit. If the carbon dioxide produced by the reaction is not vented from the fermentation chamber, for example in beer and sparkling wines, it remains dissolved in the medium until the pressure is released. For such kind of fermentation ethanol acts as the final electron acceptor (though for yeast it is a by-product), whereas glucose is the preferred electron donor (substrate) (Jackson, 2008). Vinegar is produced by this process. Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Experiments were performed to understand this process better. In this case, we’re focusing on the latter. A yeast Saccharomyces cerevisiae carries this fermentation. The process of alcoholic fermentation begins shortly after harvest, when large bins of grapes are pressed or crushed to release their juice, making a must. Examples from Classical Literature.
