Department of Mineral Biotechnologies

Head of the department: MVDr. Daniel Kupka, PhD.



Research in the department is focused on the biogeochemistry, geomicrobiology and environmental biotechnology.

Research in biogeochemistry and geomicrobiology is focused on the investigation of:

  • biogeochemical processes in the upper part of the Earth geosphere in connection with mineral weathering and global cycle of the elements,
  • microbial interactions with inorganic and organic components of the rock environment in the mineral transformation processes in mineral deposits and mine and industrial waste repositories,
  • paragenesis of secondary mineral structures,
  • biodegradation of natural and synthetic materials,
  • biodiversity of various natural matrices (soil, water, sediments).


Research in the field of environmental biotechnology is focused on the development and application of biotechnology methods for:

  • mineral processing and waste recycling,
  • improving the quality of raw materials for ceramic and glass industry,
  • remediation of old environmental burdens and sites contaminated by antropogenic activities,
  • synthesis of advanced (bio)materials and bio-composites for selective recovery of usable components from solid and liquid municipal and industrial wastes,
  • prediction and prevention of bio-corrosion of construction composite materials.


Research program in the field of mineral biotechnologies at the Institute of Geotechnics SAS was founded by Prof. Dr.h.c. Ing. František Špaldon, DrSc. in 1985. In 1992, a detached Department of Mineral Biotechnologies was established and led by assoc. prof. Ing. Mária Kušnierová, PhD. The department currently employs a group of experts in various fields of this interdisciplinary research.



Bioleaching & Metal Mobilization

  • dissolution of minerals by bacterial oxidation of iron and/or reduced inorganic sulfur compounds (RISC),
  • bacterial reductive dissolution of iron oxides,
  • liberation of iron impurities from nonmetallic by bacterial by-products.

Biocorrosion & Biodeterioration of Synthetic and Industrial Materials

  • bio corrosion of building composite materials,
  • bio-deterioration of underground storage structures.

Bioremediation of Mine and Industrial Waste Effluents

  • biodegradation, biosorption, bioprecipitation, biovolatilization,
  • bacterial dissimilatory reduction of iron, sulphate, nitrate, (per)chlorate,
  • ion exchange,
  • advanced oxidation processes (AOPs),
  • toxicity and biodegradability assessment (respirometric methods).

Degradation of Organic Pollutants in Waters and Soils

  • biodegradation of organic pollutants in soils, groundwaters and wastewaters,
  • contaminant-specific monitoring of the degradation based on the extraction of the analyte from the matrix before analysis,
  • contaminant-non-specific monitoring of organic matter mineralization based on oxygen and carbon dioxide gas analysis (respirometric methods).
