摘要: 本文对从新疆库尔勒香梨的酒精发酵液中分离得到的两株优良香梨酵母XL1和XL2的耐糖性、耐酒精度、耐SO2能力和凝集性进行了实验。结果表明:在含糖量为50%,酒精度为20%,SO2浓度为250mg/L时XL1和XL2均可发酵且凝集性强。XL2对糖度、酒精度的耐性均大于XL1,但对SO2的抵抗力小于XL1。

Abstract: The abilities ofthe tolerance ofalc oholconcentration,sugar concentr ation,sulfur dioxide concentratio n and agglutination to both Kuerle fra grant pear yeast XL1and XL2were studied.The results showed that XL1and XL2couldbothfermentthefragrantp earjuicewithsugarcontent50%,sul furdioxideconcentration250mg /La nd alcohol concentration 20%.Their ag glutination was very strong.The abi lities of XL2of adapting to alcohol and sugar werestronger thanthatofXL1,butthetoleranceabilityofXL2tosu lfurdioxidewas weaker thanthatofX L1.
