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
