Life at the limits 鈥 Algal physiology under extreme conditions
Snow algae are often found in polar and high alpine regions but can in theory bloom anywhere there is suitable snow and proper summer conditions; they are able to survive and bloom in the liquid phase of snow and ice. Outside of their active growth phase, snow algae can remain dormant, often during the long, dark and freezing temperatures of a polar winter. The project will investigate the limits of life of snow algae by subjecting the cells to various extreme conditions, including conditions analogous to Mars and the Moon. Metabolomic analysis will be carried out to reveal the metabolic pathways that allow them to thrive at these extremes. These findings will expand our understanding of physiological traits and their plasticity, as well as investigate applications for the Space exploration sector, for example, the potential of growing microalgae as 鈥淪pace crop鈥.
