The present invention relates to methods for production of 2′Fucosyllactose by a microbial system comprising a α-1,2 fucosyltransferase (FucT2) polynucleotide and a Guanosine 5′-diphospho-β-L-fucose (GDP-L-fucose) synthesis pathway using lactose as a substrate. Furthermore, the present invention relates to compositions comprising the microbial system.
