Research Interests

  • 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.

  • Culture Collection of Microalgae and Bacteria – Institute of Oceanology PAS –Biochemistry Laboratory
    • Development and maintenance of a microalgal culture collection including
      • Chlorella vulgaris (A1-76),
      • Dictyosphaerium pulchellum (C2-79),
      • Scenedesmus armatus (B1-76),
      • Scenedesmus microspina (B2-76), which represent axenic cultures of the green algae isolated from the Baltic Sea.
  • Development and maintenance of a bacterial culture collection
    • Heterotrophic bacteria from brackish water of the Southern Baltic Sea - Culture Collection IO PAS – Biochemistry Lab
