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 develop in the axils of leafy laminae. It is self-fertile. In summer 2015, large quantities of different species of "Sargassum" accumulated along the shores of many of the countries on the Caribbean Sea. Some of the affected islands and regions include the Caribbean coast of Mexico, the Dominican Republic, Barbados, and Tobago. Another large outbreak occurred in 2018. The algae wash ashore, pile up on beaches, and decay, often causing a foul odor, releasing fumes of sulphur compounds that rust metals, can turn taps black in shore houses, damage modern conveniences, and cause respiratory problems, particularly for asthmatics.
