2000-2001 Master's thesis:   “Antioxidant protection of cells induced by phenolic compounds”

Supervisor:  dr. hab. eng.  Marcin Łukaszewicz


Within the thesis chemiluminescence of luminol  was  examined in different types of buffers, as well as concentration of oxidants and pH.  Low molecular weight phenolic antioxidants (PPA-n ) were examined in vitro using the CL method.  The antioxidant properties of PYA-n compounds were evaluated and compared with the reference compound (BHT).  Both BHT and PYA-n were compared as potential inhibitors of lipid peroxidation.

  • Biosurfactants

    We identified chemical structures of newly isolated biosurfactants which are secreted by Arctic microorganisms. We are investigating their antibacterial, antifungal properties as well as proapoptotic activity. Biosurfactants can be used as an antiseptics.

  • Biogas

    We are investigating and optimizing the efficiency of metanogenesis in bioreactors. We are also testing various substrates (industrial waste) as materials for biogas production. Microorganisms which participate in this process are investigated as e.g. biofilm producers.

  • Bacteriophages

    Bacteriophages or phages are bacterial viruses. We isolated and are now investigating phages which kill Bacillus strains. Beside the basic research, the collection of phages can be used in industry as for example eliminators of infections.

  • Antiseptics

    Fungal infections are difficult to treat because of the small number of effective drugs. Candida albicans resistance depends on the activity of ABC transporters (MDR, CDR). We have investigated strains and methods for finding new antifungal compounds (synthetic and natural) e.g. probiotic yeast Saccharomyces boulardii.
