The research conducted in Biochemistry Laboratory concentrate on the following major topics:
- isolation and identification of siderophore-like substances, natural iron chelators
- isolation and identification of carotenoids in marine biota
- isolation and characterization of proteins
-
Marine biotechnology
-
marine organisms (algae and cyanobacteria) as a source of high value added products
-
application of peptidomics in environmental studies and in search for potential pharmaceuticals
-
marine biotoxins
-
Abiotic factors influencing ecophysiological processes of phytoplankton cells - growth, photosynthesis, composition and contents of pigments, and transport of metal ions through cell membranes, at present iron.
-
Allelopathic interactions between phytoplankton species.
