Main field of research:

  • Microbial transformation and degradation of recalcitrant and/or hazardous xenobiotics e.g. aromatic compounds, anti-inflammatory drugs (NSAIDs), plastics:
    • isolation of bacterial and fungal strains and design of mixed population of microorganisms able to decompose these compounds;
    • determination of genetic and biochemical mechanisms of degradation;
    • identification of key enzymes involved in the biodegradation pathways;
    • optimization of process parameters for improvement of degradation efficiency:
      • degradation under co-metabolic conditions;
      • removal of xenobiotics by free and immobilized bacterial strains;
      • the influence of abiotic and biotic factors;
  • Application of mutagenesis as a tool for an improvement of key enzymes engaged in aromatic ring fission for industrial and environmental purposes;
  • Bioremediation and phytoremediation of polluted environments:
    • interactions between bacteria-bacteria, bacteria-environment, bacteria-plant;
    • bacterial compounds promoting plant growth;
    • identification of genes determining ability of microorganisms to colonize plants;
    • changes in structural and functional (bio)diversity of microbial communities as a result of contamination and remediation;
    • construction of bacterial consortia for bioaugmentation of polluted environments;
    • application of municipal and industrial organic waste products for assisted bioremediation;
    • formulation of immobilized microorganisms able to degrade xenobiotics in wastewater treatment plants;
  • Study on susceptibility of various plastic compositions to degradation in different environments;
  • Bacterial consortia as bioindicator of water quality:
    • control of bacterial metabolic processes;
    • construction of biosensing systems;
  • Water environment management.
