Paper Title:
Isolation of Saccharomyces cerevisiae YDJ05 from the Spontaneous Fermentation Pear Wine and Study of the Yeast Growth Dynamics during the Association Fermentation
  Abstract

Five preponderant yeast strains (YDJ01, YDJ02, YDJ03, YDJ04 and YDJ05) were isolated from the spontaneous fermentation pear wine as source of yeast for wine making from pear. Ethanol yield of YDJ05 was the highest and its using rapidity of the sugar was the most quickly. YDJ05 was identified as Saccharomyces cerevisiae and named Saccharomyces cerevisiae YDJ05. In addition, the fermentation dynamics of three yeast strains (Saccharomyces cerevisiae YDJ05, “Angle” yeast and Saccharomyces cerevisiae GIM2.39) were studied including single fermentation and associated fermentation. The fermentative behavior of three strains changed in association fermentations (Saccharomyces cerevisiae YDJ05 and “Angle” yeast, Saccharomyces cerevisiae YDJ05 and Saccharomyces cerevisiae GIM2.39). Results indicated that the qualities of pear wines made from association fermentations were better than that of single fermentations. The pear wine fermented associated by Saccharomyces cerevisiae YDJ05 and Saccharomyces cerevisiae GIM2.39 was the best in quality by sensory evaluation among all pear wines whose ethanol concentration was 10.3% (v/v). Saccharomyces cerevisiae YDJ05 and mai could be excellent potential source of strains.
