Abstract

Highlights: EPS of Clavibacter michiganensis M1 is a reliable source of fucosylated oligosaccharides. A novel glucofucobiose was successfully obtained from EPS of C . michiganensis M1. Glucofucobiose is a promising candidate as prebiotics. Abstract: Fucose and fucosylated oligosaccharides have important applications in various industries owing to their prebiotic, anti-inflammatory, anticoagulant, and antiviral activities. Here, we aimed to obtain fucosylated oligosaccharides using the acidolysis method to depolymerize exopolysaccharides extracted from Clavibacter michiganensis M1. Based on structural analysis, the prepared glucofucobiose was found to consist of d -glucose and l -fucose, with a molecular weight of 326 Da and a structure of d - Glcp -β-(1→4)-l - Fucp . The prebiotic activity of glucofucobiose was compared with that of 2′-fucosyllactose (2′-FL), the most abundant oligosaccharide in human milk. According to the results, glucofucobiose could significantly promote the proliferation of six probiotic strains, and short-chain fatty acid production of five probiotic strains on glucofucobiose was substantially higher than that on 2′-FL at 48 h of fermentation. Overall, this study proposed a new technology for obtaining fucosylated oligosaccharides. The prepared glucofucobiose was found to exhibit potential prebiotic activity and should be further assessed.
