Sargassum muticum and potash for fertilization. Water treatment: the cell walls of "S. muticum" contains alginates and fucoidans. The association of both molecules forms a bigger molecule and this one can be a flocculant. This process can be a method to catch organic matter present in sewage. This flocculant, rich in proteins and oligoelements, is easily biodegradable and could be used for fertilizer. Previous studies have shown that "Sargassum muticum" is able to carry out the biosorption of heavy metals like cadmium, chlorophenolic compounds, and nickel. Antifouling: Secondary metabolites produced by marine algae could be an interesting alternative antifouling agent. Previous studies
Sargassum on wave height and current. On the Caribbean island of Saint Martin, backhoes are also used in the process of clean up once the "Sargassum" weed reaches the shorelines. Researchers say that the "Sargassum" outbreak started in 2011, but it has become worse over the years. As it is cleaned up on the shorelines, in a matter of a week, the shorelines are once again filled in masses. It is still a recurring problem to this date. Several factors could explain the proliferation of "Sargassum" in the area in recent years. These include the rise of sea temperature and the
