Abstract
The present invention provides a recombinantwith improved 2'-fucosyllactose production, and a construction method thereof. In the present invention, a strain capable of efficiently synthesizing 2′-fucosyllactose is obtained by the fusion expression of the fucosyltransferase gene and the L-fucokinase/guanosine 5′-diphosphate-L-fucose pyrophosphorylase gene inBSGL-FF, the fermentation supernatant of which comprises a cumulative amount of 2′-fucosyllactose as high as 1.62 g/L, which is 55% higher than the amount achieved with the control strain. The construction method of the recombinantof the present invention is simple, and convenient to use, and thus has good application prospects.
