Current Perspectives on the Novel Structures and Antioxidant Properties of Mangrove Endophytic Fungal Exopolysaccharides

Mangrove ecosystems are inhabited by diverse fungal endophytic communities, one of nature’s treasures of the marine biotope. Mangrove fungi comprise mostly marine fungi, and the small group of terrestrial fungi can be classified into saprophytic, parasitic, and symbiotic fungi. Fungi produce high-molecular-weight exopolysaccharides (EPSs) during their metabolic process, which plays a main role in biofilm formation and in the localization of biogeochemical processes within aggregates and sediments. In recent years, marine microbial EPSs gained momentum particularly those originating from mangrove fungi due to a specific marine environment. Mangrove fungal EPSs with unique chemical composition, diversity of structures, and properties were reportedly suitable for biotechnological applications, viz. as natural antioxidants, anticancer drugs, biosorbents, and antimicrobial agents. Knowledge of the structural characterization of EPSs could be essential to understanding the structure–function relationship of molecules. This review emphasizes the diversity of mangrove fungi and the composition, structure, and antioxidant potential of mangrove fungal EPSs.
