Yanase, in Encyclopedia of Food Microbiology (Second Edition), 2014. Beer. Zymomonas has been isolated from beer, from the surface of brewery equipment, and from the brushes of cask-washing machines. When cask and keg beers are infected with Zymomonas, the bacteria cause heavy turbidity and an unpleasant odor of rotten apples due to traces of acetaldehyde and H 2 S.

Zymomonas | Craft Beer & Brewing
