Abstract

Novel strains of yeast and methods for improved ethanol production utilizing the yeast strains are disclosed. In particular, the novel yeast strains Saccharomyces cerevisae YE1358 and YE1615 provide for increased fermentation temperature tolerance, as well as tolerance to increased levels of glucose and ethanol, and thereby provide increased ethanol production as compared to ethanol industry standard strains of Saccharomyces cerevisae . The novel yeast strains also generate decreased residual glucose than the ethanol industry standard yeasts.

Claims (1)

1. An isolated Saccharomyces cerevisiae yeast strain YE1615 having NRRL Accession No. Y-50433.
