Research topics

  • Biodegradation studies with application to soil remediation and wastewater treatment processes (nitroaromatic compounds and nitramines; crude oil; pharmaceutical compounds, pesticides and others). Air and water biofiltration in the laboratory model columns system); enzyme hydrolysis of municipal organic wastes
  • Eco-toxicological testing of environmental samples in order to evaluate an efficiency and safety of biodegradation processes (germination test, long-term vegetation experiments, microbial activity, and microbiotests (algae, daphnia and others)
  • Development of microbial biofertilizers with immobilized active compounds (isolation of endophytes; immobilization of microorganisms on different carriers; pot experiments and field trials; biochemical testing of soil, e.g., respiration, enzyme activity, etc.)
