Other organisms implicated in biopreservation

Acetic acid bacteria (AAB) are known for oxidizing various ethanol-containing substrates into a variety of vinegars, but are also used for the production of some biotechnologically important products, such as sorbo se 

Interest in the yeast Yarrowia lipolytica has also developed over the past few years, due to potentially numerous biotechnological applications. Although this organism is not considered to be a dangerous food spoilage yeast, various cases have been reported from food environments, some associated with severe damage (Rodrigues and Pais, 2000).
