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.

Key words: fragrant pear yeast, fermentation, rate of fermentation
