Methods for improving cell growth and alcohol production during fermentation

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
The invention provides compositions and methods for increasing the production of alcohol, e.g., ethanol, from a saccharide source and increasing the growth of ethanologenic cells by exposing ethanologenic cells to a compound. Preferred alcohologenic cells (cells capable of fermenting a carbon source into an alcohol) are selected from the family Enterobacteriaceae, such as, for example, Escherichia or Klebsiella. Furthermore, the methods and compositions of the invention are suitable for use in simultaneous saccharification and fermentation.
