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。
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））.
