  • MATERIALS AND METHODS FOR CREATING STRAINS OF SACCHAROMYCES CEREVISIAE THAT EXHIBIT AN INCREASED ABILITY TO FERMENT OLIGOSACCHARIDES INTO ETHANOL
    Publication number: 20210309982
    Abstract: Disclosed herein is a yeast strain capable of fermenting high maltose syrups into ethanol in the presence of glucose. In commercially important fuel ethanol yeast strains, the presence of glucose prevents robust maltose fermentation. This invention causes enhanced co-fermentation of maltose and glucose in strains otherwise identical to commercial fuel ethanol yeast strains.

  • Methods of fermenting mixtures that include di- and tri-saccharides formed at low temperature using a maltophilic yeast
    Patent number: 11078501
    Abstract: Disclosed herein are materials and methods for the production of high concentrations of ethanol from plant starch material broken down into disaccharide and trisaccharide sugars such as maltose, isomaltose, and maltotriose from uncooked starch. Herein is also described use of a yeast strain capable of fermenting high maltose syrups into ethanol without the need to convert disaccharides or trisaccharides into glucose using exogenous glucoamylases.
    Type: Grant
