Brown algae contain fucoidan, a polysaccharide with promising properties for applications in medicine and cosmetics. However, fucoidan varies in structure, composition and modifications such as degree of sulfation or molecular weight - depending on the origin and other factors. This leads to different, sometimes even opposing effects. Of course, the effect must be clear, especially for medical use. With its interdisciplinary approach, the FucoSan project aims to generate systematic knowledge of fucoidanes and their modes of action. In various test systems, the optimal fucoidan for each particular application should be found.
The project partners are developing economically and ecologically sustainable processes to harvest or acquire brown algae from the Baltic Sea.
From the brown algae Fucoidan extracts are created. These in turn are characterised in chemical and biological processes.
All test results flow into a database. On the basis of this, the scientists select the most promising candidates to test their applicability. In three pilot runs, the fucoidan extracts in the fields of ophthalmology (age-related macular degeneration), regenerative medicine (tissue engineering) and cosmetics are tested for their suitability.
At the same time, the project partners conduct market analyses and develop business models for products based on specific fucoidan extracts. Thus, the expertise that can be found in the German-Danish border region is merged into a sustainable value-added chain.
