Abstract:

Totally 120 yeast strains were isolated from longan grapes harvested from Shacheng region during spontaneous fermentation process. Five unique colonies were identified through culture and clustering analysis using WL medium. Five different genotypes were also identified through RFLP analysis of 5.8S rDNA-ITS region. The species of four yeast strains were identified through sequence analysis and another one still needs to be further identified.

Key words: longan grape, spontaneous fermentation, yeast, biodiversity
