Recombinant bacteria and the uses thereof for producing ethanol

摘要

The present invention relates to recombinant bacteria and the uses thereof, particularly for the production of ethanol. The invention also relates to methods for the production of such bacteria, as well as to nucleic acid constructs suitable for such production. The invention specifically relates to bacteria lacking a functional LDH gene and/or containing a recombinant nucleic acid encoding a PDC and ADH. The bacteria of this invention may be produced from any stress-resistant bacteria.

主权项

1. A recombinant Deinococcus bacterium comprising a recombinant nucleic acid construct encoding a pyruvate decarboxylase (PDC) from Zymomonas and an alcohol dehydrogenase (ADH) from Zymomonas, wherein the PDC and ADH coding sequences are placed in an operon in the recombinant nucleic acid construct, and wherein said recombinant nucleic acid construct is integrated into the genome of the bacterium.
