The (R)/(S) ratios of acetoin were always higher in wines obtained by Saccharomyces cerevisiae than in those obtained by Kloeckera apiculata. A significantly different behaviour was determined between the two species as regards contents and ratios of 2,3-butanediols: S. cerevisiae produced more (R,R)-2,3-butanediol (about 80%), whereas K. apiculata produced more meso-form (about 90%).

Abstract
The (R)/(S) ratios of acetoin were always higher in wines obtained by Saccharomyces cerevisiae than in those obtained by Kloeckera apiculata. A significantly different behaviour was determined between the two species as regards contents and ratios of 2,3-butanediols: S. cerevisiae produced more (R,R)-2,3-butanediol (about 80%), whereas K. apiculata produced more meso-form (about 90%).File in questo prodotto:
