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 color and consist of a holdfast, a stipe, and a frond. Oogonia and antheridia occur in conceptacles embedded in receptacles on special branches. Some species have berrylike gas-filled bladders that help the fronds float to promote photosynthesis. Many have a rough, sticky texture that, along with a robust but flexible body, helps it withstand strong water currents. Large, pelagic mats of "Sargassum" in the Sargasso Sea act as one of the only habitats available for ecosystem development; this is because the Sargasso Sea lacks any land boundaries . The Sargassum patches act as a refuge for many species in different
