Abstract: In this study,spoilage microorganisms were isolated from bottle bulged Qiangli Pipa Syrup by spread plate method.The morphological,biochemical characteristics and molecular methods were analyzed to identify the taxonomic position of the strains.Moreover,their control methods were also studied in this test.The results showed that a spoilage strain(LS2) was obtained.According to taxonomic identification,the strain LS2 was identified as Zygosaccharomyces bailii. The sterilization requirements were achieved after heat treatment at 110 ℃ for 20 min.

Key words: Qiangli Pipa Syrup, spoilage microorganisms, identification, Zygosaccharomyces bailii
