Abstract: This study establishs a rapid specific PCR assay to screen Thermoactinomyces intermedius strains and screens Thermoactino-myces intermedius strains from high-temperature daqu of sesame flavor liquor by the specific PCR assay. Experimental results show that the designed specific primers are specific for Thermoactinomyces intermedius, it is suitable for screening rapidly Thermoactinomyces intermedius strains. The specific PCR can save a lot of time and costs compared with the traditional identifying methods.

Key words: Specific PCR, Thermoactinomyces intermedius, Rapid identifying
