RAPID DETECTION OF MICROORGANISMS IN ASEPTIC PRODUCTS USING AN ATP BIOLUMINESCENT SYSTEM

摘要

There are many pasteurized milk products that can be stored at room temperature. These products are occasionally contaminated by a small number of bacteria, so it is necessary to do sterility testing using agar plates. This sterility test typically takes a long time. For example, pasteurized products are incubated at 30 °C or 37 °C for 2-3 days. Incubation followed by plate counting is time-consuming, yielding results after 3-5 days. For the purpose of shortening the time for this test, many methods have been studied including direct microscopic counting, membrane filtration, and ATP bioluminescence.
