Part VII. Production of Polyalcohols by Saccharomyces rouxii in the Concentrated Media of Sodium Chloride and Sugars, and Identification of Polyalcohols Produced

Abstract

Identification of polyalcohols which were produced in large amounts by Saccharomyces rouxii under aerobic fermentation in the concentrated media of sodium chloride and sugar, was carried out by isolating these products in crystalline form from the fermented broth. The products were determined as glycerol and D-arabitol. In the concentrated medium of sodium chloride, about 70% of the polyalcohols produced was glycerol, while in the concentrated sugar medium, the formation of D-arabitol was more markable than glycerol.
