Abstract: Disclosed are a recombinant Corynebacterium glutamicum (C. glutamicum) for producing fucosyllactose which is transformed to express ?-1,2-fucosyltransferase, GDP-D-mannose-4,6-dehydratase (Gmd), GDP-L-fucose synthase (WcaG) and lactose permease (LacY), wherein the Corynebacterium glutamicum has phosphomannomutase and GTP-mannose-1-phosphate guanylyltransferase, and a method for producing fucosyllactose using the same. According to the recombinant Corynebacterium glutamicum and the method for producing fucosyllactose according to the present invention, with use of a GRAS Corynebacterium glutamicum strain, which is safer than conventional Escherichia coli, 2?-fucosyllactose can be produced at a high concentration while overcoming drawbacks of conventional methods associated with industrial inapplicability resulting from low production concentrations.
