University of Barcelona Apr 11 2025 Every year, thousands of tonnes of brown algae are extracted from the seabed to obtain compounds such as alginates, a polymer composed of sugars that has high density and strength, offering potential biotechnological applications. An international team led by the University of Barcelona has deciphered the mechanism by which a type of enzyme, called alginate lyase (AL), is capable of degrading these marine biomaterials, allowing them to be used as carriers of
