Fuente: WIPO "tomato" Production of a mixture of neutral fucosylated oligosaccharides by a cell. The disclosure is in the technical field of synthetic biology and metabolic engineering. More particularly, the disclosure is in the technical field of cultivation or fermentation of metabolically engineered cells. The disclosure describes a cell metabolically engineered for production of a neutral mixture of at least four different neutral fucosylated oligosaccharides. Furthermore, the disclosure provides a method for the production of a neutral mixture of at least four different neutral fucosylated oligosaccharides by a cell as well as the purification of at least one of the neutral oligosaccharides from the cultivation.
