Carbon source shapes the structure and function of bacterial exopolysaccharides

Caption

Schematic illustration showing how carbon source selection influences the structure and biological properties of exopolysaccharides (EPS) produced by Bacillus velezensis AZU-A3. Sucrose-derived EPS (EPS-S) exhibited a mannose- and uronic acid-rich composition with a more ordered helical-like conformation, whereas sugarcane molasses-derived EPS (EPS-M) showed a glucose-rich composition with a more flexible molecular structure. These substrate-dependent structural differences were associated with enhanced antioxidant and antibacterial activities of EPS-M.
