About: While performing this research the methods for evaluation of proteolytic compared were compared. Environmental microorganism were isolated and screened for strains secreting extracellular proteases. Selected strains were identified using standard API tests and sequencing. In addition, culture conditions were optimized for the highest secretion of proteolytic enzymes for chosen strains. |

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.
