Surface proteins of Bifidobacterium bifidum DNG6 growing in 2'-fucosyllactose alleviating lipopolysaccharide-induced intestinal barrier injury in vitro.

Human milk oligosaccharides promote the growth and adhesion of Bifidobacteria, thus exerting multiple biological functions on intestinal epithelial cells. Bacterial surface proteins play an important role in bacterial-host intestinal epithelial interactions. In this study, we aimed to investigate the effects of surface proteins extracted from Bifidobacterium bifidum DNG6 (B.
