Disclosed in this document are genetically modified microorganisms and related methods for improved export of oligosaccharides. the microorganisms described in this document express proteins of the major enhancer superfamily, such as cdt-1, which allow the export of oligosaccharides. cdt-1 variants have higher activity towards oligosaccharide export. means for exporting oligosaccharides into the growth medium are provided in this document. |
