Glycolipopeptide biosurfactants
Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.
Process for efficient purification of neutral human milk oligosaccharides (HMOs) from microbial fermentation
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.
