  • Microbial Cells Possessing a Reduced Lactose Internalization For Producing an Oligosaccharide
    Publication number: 20240110213
    Abstract: Disclosed are genetically engineered microbial cells for the production of an oligosaccharide of interest, wherein said microbial cells possess a variant of the E. coli lactose permease LacY which exhibits a reduced transport activity for lactose, and methods for producing an oligosaccharide by using said genetically engineered microbial cells.
    Type: Application

  • Improved Export of Oligosaccharides From Bacterial Cells
    Publication number: 20230304052
    Abstract: Disclosed are genetically-engineered gram-negative bacterial cells for the production of an oligosaccharide of interest, wherein the bacterial cell possesses a saccharide transporter and/or a porin being expressed from a recombinant gene or a deregulated endogenous gene, thereby facilitating the translocation of the oligosaccharide of interest from the cell's cytoplasm into the cell's environment. Also disclosed are methods for producing an oligosaccharide of interest which used said genetically-engineered gram-negative bacterial cells.
