Abstract:

Interdelta PCR fingerprinting technology was used to differentiate 54 Saccharomyce cerevisiae strains isolated from vineyard soil, brewing equipments and spontaneous fermentation process of Longan grape in Shacheng area. Results indicated that 7 genetic patterns were distinguished by Interdelta PCR fingerprinting. The genetic patterns I through VII accounted for 31.5%, 11.1%, 7.4%, 42.6%, 3.7%, 1.85% and 1.85%, respectively. The numbers of genotypes of yeasts isolated the late stage of spontaneous fermentation, the surface of brewing equipments and vineyard soil were 4, 3 and 2, respectively. Based on the cluster analysis tree, the genetic pattern I and IV had the closest genetic relationship, and the genetic pattern VII had the most far genetic relationship with others. The distribution and variation discipline of different Saccharomyce cerevisiae strains will provide a theoretical foundation for choosing excellent strains with their own favor characteristics.

Key words: Saccharomyce cerevisiae, Interdelta PCR, differentiation and identification, cluster analysis, Shacheng area, Longan grape
