Fuente: WIPO "dairy products" The invention discloses a detection method for thermoduric bacteria in dairy products. The method comprises the following steps of 1, heating dairy products, and separating out thermoduric bacteria; 2, cultivating and counting the thermoduric bacteria separated out in the step 1; 3, selecting bacterial colonies of the typical form in the step 2 and performing streaking cultivation; 4, extracting DNA from the cultivated thermoduric bacteria, and detecting thermoduric bacteria on the extracted DNA by adopting the PCR sequence. The method has the advantages that the types and number of the thermoduric bacteria in the dairy products can be accurately authenticated, the detection method comprises the simple steps, operation is convenient, the detection time is shortened, the DNA sequencing method is adopted, and the strain identification speed and resolution ratio are increased.
