A high-temperature resistant yeast strain （grew well at 45 ℃） was screened out from stacking fermented grains of Maotai-flavor liquor and its resistance to ethanol, acid and sugar and its fermenting power were investigated. The results showed that its ethanol resistance capacity was 6 %vol, its sugar resistance capacity was 25 %, its fermenting power was 6.928 g/50 mL, the optimum pH for its growth was 5.0, and its highest tolerance temperature was at 45 ℃.
