The research group in Astrobiology and Molecular Biology of Cyanobacteria aims at deciphering the cellular and molecular basis of cyanobacterial adaptation to extreme conditions on Earth, with a focus on desiccation, ionizing and UV radiation, but also under space and Martian simulated conditions. Experiments are dealing mainly on desert cyanobacteria exposed to laboratory-planetary simulations and to space and Martian conditions in low Earth orbit in the contest of ESA space experiments. The aims are to investigate the endurance of life as we know it, identify biosignatures for searching past or present life forms on Mars and to unravel the molecular mechanisms of cyanobacterial desiccation- and radiation tolerance. On-going researches exploit also cyanobacteria for developing life-support systems for human space exploration.
Part of the Culture Collection of Microorganisms from Extreme Environments (CCMEE) established by E. Imre Friedmann is maintained in the laboratory.
