  • Publication number: 20190119314
    Abstract: The invention relates to a method for obtaining an N-acetylglucosamine containing neutral oligosaccharide from a fermentation broth, wherein said oligosaccharide is produced by culturing a genetically modified microorganism capable of producing said oligosaccharide from an internalized carbohydrate precursor, comprising the steps of: i) ultrafiltration (UF), preferably to separate biomass from the broth, ii) nanofiltration (NF), preferably to concentrate said oligosaccharide in the broth and/or reduce an inorganic salt content of the broth, and iii) treating the broth with an ion exchange resin, preferably to remove charged materials, and/or subjecting the broth to chromatography, preferably to remove hydrophobic impurities.
