“3-Fucosyllactose (3-FL) (produced by a derivative strain of Escherichia coli K-12 DH1)

Description/Definition:

3-Fucosyllactose (3-FL) (produced by a derivative strain of Escherichia coli K-12 DH1) is a purified carbohydrate powder or agglomerate containing at least 90% of 3-fucosyllactose on a dry matter basis obtained from microbial fermentation with a genetically modified strain of Escherichia coli K-12 DH1.
