Laboratory of Environmental Chemistry and Enzymology

The Laboratory of Environmental Chemistry and Enzymology focuses on the use of various types of microorganisms (fungi, bacteria and yeasts) and their secondary metabolites in the field of environmental protection.

The important part of the laboratory is The Culture Collection of Basidiomycetes, which are studied as new sources of secondary metabolites characterized by various activities (antimicrobial, antifungal, antioxidant, etc.) with potential use in the pharmaceutical industry as a new source of natural substances with biological activity.

The aim of the research is to provide an effective alternative in the form of environmentally safe substances and thus reduce the burden on the environment.

Another part of the research is focused on the study of production and immobilization of biotechnologically important enzymes whose application potential is tested in a bioreactor on real samples of water contaminated by drug residues or synthetic dyes etc.

Another area of ​​interest is the characterization and study of microorganisms in real conditions such as forest or farmland, compost, food waste, wastewater or sediment with regard to their use, for example in bioremediation, biodegradation, soil quality improvement or soil regeneration.
