  • Patent number: 11661435
    Abstract: The present application discloses a simple process for the purification of neutral human milk oligosaccharides (HMOs) produced by microbial fermentation. The process uses a combination of cationic ion exchanger treatment, an anionic ion exchanger treatment, and a nanofiltration and/or electrodialysis step, which allows efficient purification of large quantities of neutral HMOs at high purity. Contrary to the purification currently used in fermentative production of neutral HMOs, the presented process allows the provision of HMOs without the need of a chromatographic separation. The so purified HMOs may be obtained in solid form by spray drying, as crystalline material or as sterile filtered concentrate. The provided HMOs are free of proteins and recombinant material originating from the used recombinant microbial strains and thus very well-suited for use in food, medical food and feed (e.g. pet food) applications.

  • Publication number: 20220403433
    Abstract: The present invention relates to the use of one or more glycosidases in the process for the production and/or purification of a produced desired oligosaccharide. The process is preferably a microbial fermentation process using a host microorganism, which may also comprise nucleic acids expressing sugar catabolic pathway proteins suitable for the degradation of saccharides otherwise hindering the purification of the desired oligosaccharide.
