Cover Story: Succinoglycan (SG), an exopolysaccharide from Sinorhizobium meliloti, has gained attention as sustainable biomaterial due to its unique structure and tunable physicochemical properties. This review summarizes advances in SG biosynthesis, structural analysis, and chemical modifying, including oxidation, succinylation, and phenolic grafting. SG derivatives revealed improved rheological stability, antioxidant and antibacterial activities, and stimuli responsiveness. These SG modifications support the development of biodegradable multifunctional polymer platforms with enhanced barrier, mechanical, adhesive, and self-healing properties for applications ranging from food packaging films to drug delivery hydrogel. Overall, structural versatility and multifunctionality of SG suggest significant potential for future polysaccharide-based biomaterials. View this paper
