K AGAR

Alicyclobacillus are aerobic thermophilic non-pathogenic, spore forming bacteria that can survive the relatively mild pasteurization temperatures used for fruit juices and concentrates. Even very low numbers of Alicyclobacillus cause spoilage and off flavors in the beverages, damaging the brand. These bacteria are able to grow at pH values as low as 2.5 and also at elevated temperatures above 200C.Their spores survive for long period in fruit concentrates and similar environments. acidoterrestris is the most commonly occurring species that produce taints in juice and similar products, however other species may also produce taints. Acidified environment are required to detect and isolate A. acidoterrestris, therefore, K-Agar is recommended for detection of taint producing Alicyclobacillus acidoterrestris as per IFU.

for isolation and cultivation of Alicyclobacillus in fruit juices in accordance with O?cial method of IFU
