2005-2006 Master's thesis:  “Functional analysis of flax delta12 desaturase in yeast”

Supervisor: Dr. Anna Krasowska


The thesis examined fad2 desaturase enzyme activity derived from flax Linum usitatissimum in yeast Saccharomyces cerevisiae - the parent strain and deletion mutants without superoxide dismutase . Transformed yeast strains with fad2 desaturase gene were examined for  the sensitivity to various oxidants.  Lipid composition in plasmalema was analyzed in tested strains of yeast.

  • 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.
