Abstract

Official abstract text for this publication.

Disclosed is a method for producing 3-fucosyllactose using a wild Corynebacterium glutamicum strain. In addition, using the Corynebacterium glutamicum strain, which is a GRAS strain, 3-fucosyllactose can be produced at a high concentration, high yield and high productivity.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of producing 3-fucosyllactose comprising culturing in a medium supplemented with lactose a recombinant Corynebacterium glutamicum transformed to express α-1, 3-fucosyltransferase, transformed to express GDP-D-mannose-4, 6-dehydratase, transformed to express GDP-L-fucose synthase, and transformed to express lactose permease, and isolating 3-fucosyllactose from the medium, wherein the recombinant Corynebacterium glutamicum has phosphomannomutase and GTP-mannose-1-phosphate guanylyltransferase. 2. The method according to claim 1 , wherein the medium further comprises glucose. 3. The method according to claim 2 , wherein the production of the 3-fucosyllactose is carried out by batch culture or fed-batch culture comprising further supplying glucose or lactose. 4. The method according to claim 1 , wherein the recombinant Corynebacterium glutamicum is transformed to overexpress phosphomannomutase, and is transformed to overexpress GTP-mannose-1-phosphate guanylyltransferase.
