| Relevance | A method for improving production of ethanol by fermenting xylose-containing mixed sugars using Z. mobilis strains. |
| Type of claims | Publication |
| Overview | This patent discloses a method of improving ethanol production by xylose-utilizing Z. mobilis strain ZW658. The medium includes sorbitol, mannitol, galactitol, or ribitol (also called adonitol), which results in increased xylose utilization and increased ethanol production. A method comprises, A) providing recombinant Zymomonas cells capable of converting xylose to ethanol, B) providing a suitable medium comprising a mixed sugar composition comprising xylose and at least one additional sugar, and one sugar alcohol selected from the group consisting of sorbitol, mannitol, galactitol, and ribitol and C) contacting (A) with (B) whereby the Zymomonas cells produce ethanol. |
