    摘要: Disclosed herein are systems and methods for the purification of human milk oligosaccharides (HMOs). The HMOs can be purified from a suspension containing one or more of a bacterial biomass, cell fragments, small particles, and biomolecules. Advantageously, the solution can be pre-treated prior to centrifuging to form a clarified supernatant containing purified HMOs.

    摘要: The present invention relates to a genetically modified cell expressing an α-1,2-fucosyltransferase and an α-1,3-fucosyltransferase, and a transporter protein of the major facilitator superfamily (MFS) and to a method for recombinant production of human milk oligosaccharides (HMOs) using said genetically modified cell. More particularly, the invention provides a method for recombinant production of and a genetically modified cell capable of producing difucosyllactose (DFL) as the most abundant HMO, with a relatively low content of 3-fucosyllactose (3FL) and/or 2′-fucosyllactose (2′FL).
