Isolation and preliminary classification of the wine-related wild yeast strains from qilian wine region

In the test, the material from Qilian wine region vineyards fermentated naturally to screen wine-related wild yeast strains 68. The YEPD medium morphological observation, WL nutrient medium clustering analysis and physiological and biochemical tests were used to classificate initially. The result showed that wine-related wild yeast strain including Candida, H.uvarum, Brettanomyces, Pichia, Rhodotorula and Saccharomyces cerevisiae, in which H.uvarum and Brettanomyces were predominant strains.
