Our team intensively works on two strong research areas. Our first task is biocontrol of human pathogenic microorganisms. Skin infections caused by microorganisms represent a clinical challenge, due to them being widespread and their ability to cause mortality of the patients. The increasing resistance of the microorganisms to antibiotics and antifungal agents is promoting the search for new compounds and methods for the treatment of skin diseases as well as understanding the physiology and metabolic plasticity of the infectious microorganisms. A combination of novel chemical compounds along with pulse electric field (PEF) technology allows us to perform a wide scale biocontrol of skin pathogens.Another research area of ours is development and improvement of new different biocatalysts by protein engineering methods. Our main target is recombinant lipolytic enzymes of Geobacillus bacteria that can be applied in the production of biofuel, fragrance and flavour esters, detergents, etc. Our study scope also encompasses microbial ureases, involved in biocementation processes and nitrate reductases which can be applied for biological production of silver nanoparticles.
