  • with improved ethanol production in medium containing concentrated sugars and acetate
    Patent number: 7897396
    Abstract: Through screening of a Zymomonas mutant library the himA gene was found to be involved in the inhibitory effect of acetate on Zymomonas performance. Xylose-utilizing Zymomonas strains further engineered to reduce activity of the himA gene were found to have increased ethanol production in comparison to a parental strain, when cultured in mixed-sugars medium comprising xylose, and, in particular, in the presence of acetate.
    Type: Grant
    Filed: October 30, 2008
    Date of Patent: March 1, 2011
    Assignees: E.I. du Pont de Nemours and Company
