Provided herein are host cells capable of producing a human milk oligosaccharide (HMO), such as yeast cells that include one or more heterologous nucleic acids encoding one or more enzymes of the HMO biosynthetic pathway, such as a fucosyltransferase, GDP-mannose dehydratase, lactose permease, and/or fucose synthase. Also provided are fermentation compositions including the disclosed host cells, as well as related methods of producing and recovering HMOs generated by the host cells.

The present invention relates to a microorganism introduced with 2-fucosyltransferase and a method for producing 2-fucosyllactose using the same, and the fucosyltransferase derived from the microorganism of the present invention is safe and has high activity compared to conventional enzymes derived from Helicobacter pylori.

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.
