Resilience of <i>Chlorella vulgaris</i> to Simulated Atmospheric Gas Compositions of Mars, Jupiter, and Titan.

ABSTRACT: This study investigates the resilience of the unicellular green microalga Chlorella vulgaris to extreme atmospheric conditions simulating those of Mars, Jupiter, and Titan. Using Earth as a control, experiments were conducted under autotrophic and mixotrophic conditions to evaluate the organism's photosynthetic efficiency, oxygen production, and biomass growth over 2, 5, and 12 days. Photosynthetic performance was analyzed through chlorophyll a fluorescence induction (JIP-test), metabolic activity via gas chromatography, and biomass accumulation measurements. Despite the extreme atmospheric compositions-ranging from the CO₂-rich, low-pressure Martian atmosphere to the anoxic atmospheres of Jupiter and Titan-C. vulgaris demonstrated resilience and a functional photo
