5. Conclusion

Marine biodiversity is a natural source of diversity in the chemical structures of the metabolites it produces. The microbial component is still the least known and the least studied, but probably a potential source of new molecule discoveries in the years to come. Bacterial exopolysaccharides of marine origin are among the molecules with strong biotechnological potential, either in their native state or after chemical and especially enzymatic modification. The ability to control this production upstream, via genetic engineering or, more simply, through knowledge of the biosynthesis mechanisms, is a promising avenue for the future. In the meantime, industrial development of these marine exopolysaccharides remains relatively limited, as they, like other EPS, come up against a major problem: their production cost, which, depending on the application, must be compatible with economic realities....
