Web1 de set. de 2011 · High osmotic pressure, low water activity (a w), and toxic effects of higher ethanol levels are the key factors [32, 69], along with other stress factors, responsible for inhibition of yeast growth and decreased fermentation performance under high substrate concentrations (Fig. 1). Ethanol is a 2-carbon alcohol. Its molecular formula is CH3CH2OH. An alternative notation is CH3−CH2−OH, which indicates that the carbon of a methyl group (CH3−) is attached to the carbon of a methylene group (−CH2–), which is attached to the oxygen of a hydroxyl group (−OH). It is a constitutional isomer of dimethyl ether. Ethanol is sometimes abbreviated as EtOH, using the common organic chemistry notation of representing the ethyl group (C2H5−) with Et.
