Research article: Biotransformation of Unsaturated Aliphatic Aldehydes Using Baker’s Yeast

Actively fermenting baker’s yeast (Saccharomyces cerevisiae) not only converts aliphatic aldehydes to the corresponding alcohols, but also may reduce certain carbon-carbon double bonds in the same molecule. Furthermore, an in situ acyloin condensation reaction occurs; this bioconversion reaction gives rise to relatively good yields of unsaturated 2,3-diols, which have two carbon atoms more than the corresponding aliphatic aldehyde used as substrate. Baker’s yeast has been used as a reagent in organic synthesis since the beginning of the 20th century, when fundamental studies were initiated on the mechanism of formation of fusel alcohols from the corresponding l-amino acids during the formation of ethanol.
