Alginate lyase is widely used in the biotechnology and food industries due to its ability to break down alginate, a polysaccharide found in brown algae. In the food industry, it is utilized to modify the texture and viscosity of alginate-based products, enhancing their quality and stability. In biotechnology, it plays a crucial role in the production of oligosaccharides, which have applications in pharmaceuticals and as bioactive compounds. Additionally, alginate lyase is employed in environmental biotechnology for the degradation of algal biomass, aiding in the management of algal blooms and the production of bioenergy. Its application in medical research includes the preparation of alginate-derived materials for wound healing and drug delivery systems.
