  • Materials and methods for creating strains of that exhibit an increased ability to ferment oligosaccharides into ethanol
    Patent number: 12203111
    Abstract: Disclosed herein is a yeast strain capable of fermenting high maltose syrups into ethanol in the presence of glucose. In commercially important fuel ethanol yeast strains, the presence of glucose prevents robust maltose fermentation. This invention causes enhanced co-fermentation of maltose and glucose in strains otherwise identical to commercial fuel ethanol yeast strains.
    Type: Grant

  • Expression of maize codon optimized proteins in pseudomonas fluorescens
    Patent number: 9534218
    Abstract: Compositions and methods for improving expression of a recombinant protein or polypeptide of interest in a host cell are provided. Compositions comprising a polynucleotide coding sequence for a BTBooster are provided using a plant optimized system. The coding sequences can be used in vector constructs or expression systems for transformation and expression of a recombinant protein or polypeptide of interest in a host cell. Methods comprising the codon optimization of a polynucleotide coding sequence for increased expression in a bacterial host are provided. The codon optimization method can be used in designing a polynucleotide coding sequence which expresses robust levels of protein in a bacterial host cell.
