Advances in Application of Alginate Lyase And Its Enzymatic Hydrolysate

Alginate is a linear, water-soluble acidic seaweed polysaccharide composed of L-guluronic acid and its C5 epimer D-mannuronic acid, a general term for hydrophilic derivatives of alginic acid. It is widely found in various brown algae. Alginate lyase and its enzymatic hydrolysate have a variety of biological activities and become a new research hotspot. This paper reviews the source, classification, enzymatic mechanism and enzymatic properties of alginate lyase, and summarizes the function and application of alginate lyase and its enzymatic hydrolysate brown algal oligosaccharide, in order to provide a base for the development and application of alginate lyase and its products.
