2006-2007 Master's thesis:  “Arctic origin microorganisms characterization”

Supervisor: Dr. Anna Krasowska


The thesis focused on isolation of microorganisms (bacteria and fungi) from water and soil samples delivered from Spitsbergen. Isolated microorganisms were identified using API biochemical tests and by sequencing 16S RNA subunits. In addition, the abilities of identified microorganisms to degrade petroleum derived compounds,  fat and proteins  were tested.

  • 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.
