Abstract: Provided herein are host cells capable of producing a human milk oligosaccharide (HMO), such as yeast cells that are deficient in expression or activity of an endogenous oxidoreductase. 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.
