Alcoholic fermentation allows roots of some plants to survive short periods of flooding. Ethanol does not acidify the tissues as does lactic acid, avoiding possible damage from low pH.137138 Goldfish can also use the ethanolic fermentation for short times, excreting the ethanol.139... 

Conversion of pyruvate into ethanol is a variant of cytosolic fermentation, which occurs, for instance, in yeast and hypoxia-tolerant fish, such as crucian carp and goldfish (van Waarde et al. 1993 Lutz and Nilsson 1997). Ethanol...
