Abstract
Disclosed is a method for improving the productivity of 2'-fucosyllactose (2′-FL) through enzymatic treatment. Lactose used as a substrate in the stationary phase during culture is degraded by treatment with a small amount of enzyme, the resulting glucose is consumed to produce guanosine diphosphate-L-fucose as a precursor of 2′-fucosyllactose, and the use of lactose left after culture can be maximally utilized for the production of 2′-fucosyllactose. As a result, it is possible to increase the productivity of 2′-fucosyllactose in an economically efficient manner because additional glucose is not required while minimizing by-products.
