摘要
从酱香型白酒堆积发酵醅中筛选得到1株在45℃生长良好的耐高温酵母菌,对其耐乙醇、耐酸、耐糖能力及发酵力进行了研究。结果表明,该菌耐乙醇能力为6%vol,最适pH值为5.0,耐糖能力为25%,发酵力为6.628 g/50 mL,生长耐受最高温度为45℃。
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 ℃.
