Information: 2009-2010 Master's thesis "The impact of biosurfactants on lipases activity from selected psychrotolerant microorganisms" Supervisor: Dr. Anna Krasowska 2008 Bachelor: "Probiotics as an example of functional food" Supervisor: Dr. Anna Krasowska |
About: The thesis established selected physicochemical properties of the studied biosurfactants (CMC, droplet collapse test, emulsification of petroleum ether). In addition antiadhesive activity against Candida albicans was evaluated. Preliminary studies on chemical structure of selected biosurfactants were performed. The impact of biosurfactants on the activity of lipase secreted by psychrotolerant microorganisms was 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.
