In this study, 12 yeast strains were isolated from Maotai distiller's grains, then they were cultivated at 37 to 47 ℃, and they were identified through colony morphology analysis and physiological and biochemical analysis. The results suggested that, 2 yeast strains grew well at 47 ℃ and named No.1 and No.2 strain, and they were identified as Torulopsis and Brettanomyces according to their morphological features(colony, cells, ascospores, pseudohyphae and ballistospore) and their biological and biochemical ...
