Alginate lyases,also known as alginases or alginate depolymerases,catalyze the degradation of alginate that enriched in the brown algae(Phaeophyceae).Lyases have been isolated from a wide range of organisms.This review catalogs the major characteristics of these lyases,the methods for analyzing these enzymes,as well as their biological roles.Characterization of alginate lyases will enhance and expand the use of these enzymes to engineer novel alginate polymers for applications in various industrial,agricultural,and medical fields.Its value-increment utilization in marine algal polysaccharides is a significant topic in marine biotechnology.In this review,we explore both past and present applications of alginate and alginate lyases and discuss their future prospects.;
