Algae and Cyanobacteria From Extreme Environments

''Our mission is to assess the diversity of algae and cyanobacteria in various extreme environments, their survival limits and adaptation mechanisms.''


We are open to a wide spectrum of collaboration with partners from applied research, industry, and state and non-profit organisations.

- Isolation, purification and characterization of algal strains

- Providing an evolutionarily diverse set of valuable algal strains


We are looking for cooperation with academic partners as well as public and private organizations in the fi elds of algal ecology and biotechnologies.

Know-how & Technologies

The application potential connected with our research lies in the utilization of algae and cyanobacteria from extreme environments to produce many high-value chemicals, such as polyunsaturated fatty acids, carotenoids and phosphatidylglycerol – the health-beneficial compounds used as nutraceuticals and pharmaceuticals and in cosmetics, among many other uses. Our main scientific focus is aimed at:

- Ecology of phytoplankton and phytobenthos in polar and mountain lakes

- Recovery of mountain ecosystems from acidity

- Diversity, ecology and ecophysiology of snow algae

- Algae and cyanobacteria as producers of compounds interesting for biotechnology

- Diatom research as bioindicators of environmental and climatic changes in polar ecosystems for paleoecological recontructions

Content of Research

As primary producers, algae and cyanobacteria are important components of both natural and man-made extreme environments such as snow, hot springs, polar or acid lakes.

Our current research projects are focused on polar and mountain photoautotrophic microorganisms, with an aim to understand their ecology, diversity and biogeography. We combine field sampling and laboratory experiments to address important questions from the autecological to the ecosystem level. We also study the impact of anthropogenic acidification on the structure of assemblages and the constraints of their biological recovery.

Main Capabilities

- Algae and cyanobacteria isolation and cultivation – bringing them from extreme conditions to the laboratory

- Optimisation of growth conditions and production of target compounds

- Assessment of ecological status of aquatic environments based on physico-chemical characteristics and the species composition of algae and cyanobacteria

Key Research Equipment

Equipment for field sampling and measurement of basic physico-chemical parameters in aquatic environments, fully equipped laboratory for:

- Isolation, and cultivation of algal strains

- Molecular characterization of strains

- Optical, fluorescent, scanning and transmission electron microscopy
