Synergistic degradation of fucoidans in the ocean

TL;DR - A Nature study finds that efficient oceanic fucoidan degradation relies on complementary bacterial guilds that cooperatively break down backbone and side-chain sugars. This conserved, globally relevant mechanism helps explain microbial control of marine carbon cycling.

• Different bacterial guilds perform complementary steps in fucoidan degradation.
• Cooperation targets both the polysaccharide backbone and its side-chain sugars.
• The mechanism appears conserved and relevant across global ocean environments.
• These microbial interactions influence how fucoidan-derived carbon is processed in marine ecosystems.
