Kikkoman’s LuciPac A3 sanitation system, distributed by Weber Scientific, measures adenosine triphosphate (ATP), which all living organisms contain, as well as monophosphate or diphosphate. The application of bioluminescence for monitoring sanitation and hygiene is a valuable tool for measuring the efficacy of cleaning and sanitation. Bioluminescent systems measure the presence of ATP in a sample using an enzyme system; conventional systems that test for ATP alone may neglect the true presence of contamination.
