Abstract:

To isolate and screen characteristic yeast strains, 210 yeast strains were isolated from soils from three Longan grape plantations in Shacheng region by gradient dilution and streak plate methods. These stains were classified into nine groups according to their morphological phenotypes, and the nine groups were identified by 5.8S ITS restriction fragment length polymorphism (RFLP) analysis, and two of them, Issatchenkia orientalis and Candida tropicalis, were common yeast strains. This study confirms the biodiversity of yeast in the oil of this region.

Key words: Longan vineyard, soil, yeast, morphological phenotypes RFLP method, biodiversity
