  • Fermentation process
    Patent number: 4242454
    Abstract: A fermentable sugar feed is continuously converted by fermentation to dilute aqueous ethanol ("beer") in a series of agitated fermentation vessels which contain progressively more ethanol and less fermentable sugar. At least two strains of yeast are selected for the fermentation, one of which provides a high rate of ethanol production in a fermentation medium containing a relatively low concentration of ethanol and a relatively high concentration of fermentable sugar and the other of which provides a high rate of ethanol production in a fermentation medium containing a relatively high concentration of ethanol and a relatively low concentration of fermentable sugar.
