Fucoidans and fucoidanases--focus on techniques for molecular structure elucidation and modification of marine polysaccharides.

The research field of fucoidans (sulphated polysaccharides from algae) and fucoidanases was strongly developing in recent years. Several different fucoidans and a few fucoidan-degrading enzymes were isolated and characterised. A high potential is seen in the medical exploitation of the fucoidans and its degradation products. This review gives an overview about the research of the last 5 years concerning fucoidan characterisation and application as well as enzyme detection, characterisation and production.
