  • IMPROVED OLIGOSACCHARIDE PRODUCTION IN YEAST
    Publication number: 20220298536
    Abstract: Provided herein are genetically modified yeast cells capable of producing one or more human milk oligosaccharides (HMOs) and methods of making such cells. The yeast cells are engineered to comprise a heterologous nucleic acid encoding a transporter protein and one or more heterologous nucleic acids that encode enzymes of a HMO biosynthetic pathway. Also provided are fermentation compositions including the disclosed genetically modified yeast cells, and related methods of producing and recovering HMOs generated by the yeast cells.

  • Biosynthesis of compounds in yeast
    Patent number: 10519475
    Abstract: Provided herein are genetically modified yeast cells capable of producing one or more human milk oligosaccharides. The yeast cells include one or more heterologous nucleic acids that encode enzymes of a human milk oligosaccharide biosynthetic pathway. The yeast cells do not include a heterologous nucleic acid encoding a fucokinase. Also provided are fermentation compositions including the disclosed genetically modified yeast cells, and related methods of producing and recovering human milk oligosaccharides generated by the yeast cells.
