Insights are given into how and why cyanobacteria could play a role in the development of self-sustainable manned outposts on Mars, and a wide range of life-support biological processes based on Martian resources.
Supporting Mars exploration: BIOMEX in Low Earth Orbit and further astrobiological studies on the Moon using Raman and PanCam technology

Results have implications for the hypothesis that, during Mars's climatic history, desiccation- and radiation-tolerant life-forms could have survived in habitable niches and protected niches while transported.
Dried Biofilms of Desert Strains of Chroococcidiopsis Survived Prolonged Exposure to Space and Mars-like Conditions in Low Earth Orbit.
Biofilms recovered better than their planktonic counterparts, accumulating less damage not only when exposed to UV radiation under space and Mars-like conditions but also when exposed in dark conditions to low Earth conditions and laboratory control conditions.
Investigation of neutron radiation effects on polyclonal antibodies (IgG) and fluorescein dye for astrobiological applications.
Antibodies and fluorescent dyes, freeze-dried and in buffer solution, were irradiated with 0.6 MeV and 6 MeV neutrons and sample analyses demonstrated that, in the conditions tested, antibody recognition capability and fluorescence dye intensity are not affected by the neutrons.
The Development of an Effective Bacterial Single-Cell Lysis Method Suitable for Whole Genome Amplification in Microfluidic Platforms
This work presents a lysis protocol that can be used to extract genomic DNA from both gram-positive and gram-negative species without interfering with the amplification chemistry.
Limits of Life and the Habitability of Mars: The ESA Space Experiment BIOMEX on the ISS
The presented BIOMEX concept could be scaled up to future exposure experiments on the Moon and will serve as a pretest in low Earth orbit.

Ground-based simulations of the BIOMEX experiment aimed at investigating the endurance of extremophiles and stability of biomolecules under space and Mars-like conditions showed no significant damaging effect on the tested cyanobacterial biosignatures, pointing out the relevance of the latter for future investigations after the EXPOSE-R2 mission.
Avoidance of protein oxidation correlates with the desiccation and radiation resistance of hot and cold desert strains of the cyanobacterium Chroococcidiopsis
Results suggest that in the investigated strains a tight correlation occurs between desiccation and radiation tolerance and avoidance of protein oxidation.
Endurance of the endolithic desert cyanobacterium Chroococcidiopsis under UVC radiation
In survivors repair mechanisms were responsible for the recovery of the induced damage to genome and photosynthetic apparatus and the accumulation of carotenoids contributed to UVC resistance by providing protection against oxidative stress.
