Abstract: A process has been developed for the utilization of fructose by PTS? microorganisms. Providing the microorganisms with increased fructokinase activity, and optionally with increased fructose transport capacity, allows the microorganisms to use fructose as a nutrient supply with sustained growth. The microbial production of substances such as cell mass, glycerol, and 1,3-propanediol may be achieved during growth in a fructose containing medium using this process.

Abstract: Xylose-utilizing Z. mobilis strains were found to have improved ethanol production when grown in medium containing mixed sugars including xylose if sorbitol or mannitol was included in the medium. The effect was seen in concentrations of mixed sugars where no growth lag period occurs, as well as in higher sugars concentrations.

Abstract: This invention relates to isolated nucleic acid fragments encoding trehalose metabolism enzymes, more specifically, alpha, alpha-trehalase, alpha, alpha-trehalose-phosphate synthase or trehalose-6-phosphate phosphatase. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the alpha, alpha-trehalase, alpha, alpha-trehalose-phosphate synthase or trehalose-6-phosphate phosphatase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the alpha, alpha-trehalase, alpha, alpha-trehalose-phosphate synthase or trehalose-6-phosphate phosphatase in a transformed host cell.

Abstract: This invention relates to an isolated nucleic acid fragment encoding a disease resistance factor. The invention also relates to the construction of a chimeric gene encoding all or a substantial portion of the disease resistance factor, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the disease resistance factor in a transformed host cell.

The invention also relates to the construction of a chimeric gene encoding all or a substantial portion of the disease resistance factor, in sense or anti-sense orientation, wherein expression of the chimeric gene results in production of altered levels of the disease resistance factor in a transformed host cell.

Abstract: This invention relates to isolated nucleic acid fragments encoding fructosyltransferases. More specifically, this invention relates to polynucleotides encoding 1-FFTs, 6-SFTs, or 1-SSTs. The invention also relates to the construction of a recombinant DNA constructs encoding all or a portion of the fructosyltransferases, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the fructosyltransferases in a transformed host cell.
