Application

Alginic acid, alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae. Alginate is biocompatible and gels in the presence of divalent cations such as calcium making it useful for cell encapsulation and immobilization. Immobilized cells have use in bioproduction and bioremediation processes.
