【摘要】 对经60Co诱变筛选得到的高产酒精酵母Co-158菌株的耐酒精性、耐糖性、耐酸性、耐盐性进行研究,结果表明,Co-158菌株耐酒精能力强,在含乙醇19%vol的麦芽汁培养基中10h可发酵;耐糖能力高,在葡萄糖浓度达到55%(w/v)时可发酵;耐酸碱能力强,在pH值为2.5～13.0范围内可发酵;耐盐能力强,在11%(w/v)盐溶液中仍然可发酵。更多还原

【Abstract】 The alcohol-endurance,acid-alkali resistance and salt tolerance of high-yield Saccharomycetes strain Co-158(produced by 60Co mutation) were investigated.The results suggested that Co-158 strain had strong alcohol-endurance(it could ferment in the wort culture medium containing 19 %vol ethanol),high sugar tolerance(it could ferment in the wort culture medium containing grape sugar 55 %(w/v)),high acid-alkali resistance(it could ferment in the condition of pH 2.5～13.0) and high salt tolerance(it could ferment in the wort culture medium containing salt 11 %(w/v)).更多还原
