| 20090286293 | ETHANOL PRODUCTION IN NON-RECOMBINANT HOSTS - Non-recombinant bacteria that produce ethanol as the primary fermentation product, associated nucleic acids and polypeptides, methods for producing ethanol using the bacteria, and kits are disclosed. | 11-19-2009 |
| 20100112656 | RE-ENGINEERING BACTERIA FOR ETHANOL PRODUCTION - The invention provides recombinant bacteria, which comprise a full complement of heterologous ethanol production genes. Expression of the full complement of heterologous ethanol production genes causes the recombinant bacteria to produce ethanol as the primary fermentation product when grown in mineral salts medium, without the addition of complex nutrients. Methods for producing the recombinant bacteria and methods for producing ethanol using the recombinant bacteria are also disclosed. | 05-06-2010 |
| 20100196978 | Recombinant Host Cells and Media for Ethanol Production - Disclosed are recombinant host cells suitable for degrading an oligosaccharide that have been optimized for growth and production of high yields of ethanol, and methods of making and using these cells. The invention further provides minimal media comprising urea-like compounds for economical production of ethanol by recombinant microorganisms. Recombinant host cells in accordance with the invention are modified by gene mutation to eliminate genes responsible for the production of unwanted products other than ethanol, thereby increasing the yield of ethanol produced from the oligosaccharides, relative to unmutated parent strains. The new and improved strains of recombinant bacteria are capable of superior ethanol productivity and yield when grown under conditions suitable for fermentation in minimal growth media containing inexpensive reagents. Systems optimized for ethanol production combine a selected optimized minimal medium with a recombinant host cell optimized for use in the selected medium. Preferred systems are suitable for efficient ethanol production by simultaneous saccharification and fermentation (SSF) using lignocellulose as an oligosaccharide source. The invention also provides novel isolated polynucleotide sequences, polypeptide sequences, vectors and antibodies. | 08-05-2010 |

| 20120058530 | ENGINEERING THE PATHWAY FOR SUCCINATE PRODUCTION - This invention relates to the biocatalysts for the efficient production of succinic acid and/or other products from renewable biological feedstocks. The biocatalysts have a very high efficiency for the growth-coupled production of succinic acid and/or other products from carbohydrate feed stocks as a result of both genetic manipulations and metabolic evolution. More specifically, certain biocatalysts of the present invention produce succinic acid at high titers and yield in mineral salts media during simple pH-controlled, batch fermentation without the addition of any exogenous genetic material. The genetic manipulations of the present invention are concerned with the energy-conserving strategies coupled with the elimination of alternative routes for NADH oxidation other than the routes for succinic acid production. The biocatalysts contain glucose-repressed gluconeogenic phosphoenol pyruvate carboxykinase (pck) depressed by genetic modifications and a genetically-inactivated phosphotransferase system. In terms of succinic acid production efficiency, the biocatalysts of the present invention are functionally equivalent to succinate producing rumen bacteria such as | 03-08-2012 |
