Short wave ultraviolet light (UVC) disinfection of surface - Inhibition of Alicyclobacillus acidoterrestris spores on agar medium

Abstract

Alicyclobacillus species are thermoacidophilic spoilage spore-formers found in soil. The spores can survive the normal hot fill processes that are carried out on commercial fruit juices. It seems likely that fruit in contact with soil are susceptible to contamination by Alicyclobacillus. Beverage ingredients e.g. liquid sugar are also a potential contamination sources. Alicyclobacillus has also been isolated from citrus processing lines.
