Isolation and identification of yeasts related to wine spoilage
Using 3 culture mediums and 3 isolation methods,23 yeast strains were isolated from 5 spoiled wine samples collected from Helan Mountain East Wine Region.These yeast strains were initially classified into 4 cultured types based on morphological identification.The sequence analysis for 26S rDNA D1/D2 domain gene showed that representative strains from these 4 cultured types belonged to 3 genus and 3 species:Saccharomyces cerevisiae,Hanseniaspora uvarurn and Cryptococcus triedmannii.
