[0002] In recent years, ATP bioluminescence method has been widely used in food production and processing, packaging disinfection evaluation, production environment hygiene and safety quality testing, and evaluation and detection of microbial contamination on hospital environment object surfaces and medical staff hands. This method is based on the principle that ATP and luciferin released from microbial cells produce fluorescence under the catalysis of luciferase, and the fluorescence intensity is proportional to the ATP content, which is directly related to the number of live microorganisms. This method is simple, fast and highly sensitive, and can complete the detection within a few minutes. It has very important practical significance for health supervision management and microbial contamination prevention and control.

However, in this way, due to the poor stability of the luciferase involved in the reaction, its activity is easily reduced or inactivated during packaging, storage and transportation, thereby affecting the authenticity and reliability of the test results.
