Acetobacter

A genus of rod-shaped, flagellated or nonmotile bacteria that oxidise ethanol to acetic acid.
Habitat Acetobacter spp are found on fruits and vegetables, and in souring juices. There are no reports in the literature suggesting that Acetobacter aceti is pathogenic in humans or animals. While Acetobacter spp are used commercially to produce vinegar, and to acidify some ales, they can destroy fermenting wine.

After fermentation we suppress the activity of acetobacter by either storing the wine at a temperature below 45[degrees]F or by maintaining in the wine a level of sulfur dioxide that inhibits further yeast activity.
