Dried biofilms and dried multilayered planktonic counterparts obtained from three desert strains of Chroococcidiopsis were exposed to low Earth conditions by using the EXPOSE-R2 facility outside the International Space Station. During the space mission, samples in Tray 1 (space vacuum and solar radiation, from λ ≈ 110 nm) and Tray 2 (Mars-like UV flux, λ > 200 nm and Mars-like atmosphere) received total UV (200-400 nm) fluences of about 4.58 × 102 kJ/m2 and 4.92 × 102 kJ/m2, respectively, and 0…

Biomarker Preservation and Survivability Under Extreme Dryness and Mars-Like UV Flux of a Desert Cyanobacterium Capable of Trehalose and Sucrose Accumulation

Unraveling how long life can persist under extreme dryness and what kind of environmental extremes can be faced by dried microorganisms is relevant to understand Mars habitability and to search for

Response of Endolithic Chroococcidiopsis Strains From the Polyextreme Atacama Desert to Light Radiation

A comprehensive analysis of multiple lines of defense against harmful sun radiation was conducted to diagnose the response of two Chroococcidiopsis strains isolated from different endolithic microhabitats and lithic substrates, and identify its relation with the original microenvironmental conditions of each strain.

The Cyanobacterium Chroococcidiopsis and Its Potential for Life on Mars

A member of the genus Chroococcidiopsis is likely the best organism for exploring the potential for life on Mars, however, many strains exist on Earth that still must be explored to find the best suited one.

A substantial proportion of the D. geothermalis population remained viable under all stress conditions tested, and in most cases the biofilm form proved advantageous for surviving space and Mars-like conditions.

Evaluation of the Resistance of Chroococcidiopsis spp. to Sparsely and Densely Ionizing Irradiation.

Studying the resistance of cyanobacteria to ionizing radiation provides relevant information regarding astrobiology-related topics including the search for life on Mars, lithopanspermia, and

Effects of a simulated martian UV flux on the cyanobacterium, Chroococcidiopsis sp. 029.

Under the intense martian UV flux the morphological signatures of life can persist even after viability, enzymatic activity, and pigmentation have been destroyed, showing implications for the survival of diverse microbial contaminants dispersed during the course of human exploratory class missions on the surface of Mars.

Ionizing-Radiation Resistance in the Desiccation-Tolerant CyanobacteriumChroococcidiopsis

The radiation resistance ofroococcidiopsis strains may reflect the ability of these cyanobacteria to survive prolonged desiccation through efficient repair of the DNA damage that accumulates during dehydration.
