Information: 2009-2010 Master's thesis "The influence of extremely flow frequency magnetic field on eukaryotic organisms" Supervisor: dr hab. eng. Marcin Łukaszewicz |
About: The thesis examined the impact of the magnetic field with a frequency of 50 Hz on eukaryotic organisms (yeast Saccharomyces cerevisiae and leukemia cell lines HL-60 and Jurkat T). The influence of the magnetic field on DNA, amount of free radicals and calcium level were evaluated |

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.
