With their high bioenergy output and value-added chemical compounds, microalgae ahave great potential for the biotechnology industry. Their fast adaptation ability facilitated them to rule several ecosystems including freshwater, marine, brackish, and alkaline water systems, hot spring water resources, caves, and deserts where light and water present. Covered by snow and glaciers which represents one of the hardest environmental conditions for living organisms, Antarctica is not an exception and hosts several algal species. This research aims to understand the distribution and composition of the snow microalgae of Dismal Island (68°05′S-68°51′W) and Horseshoe island (67°51′S-67°12′W), to create a psychrophilic-psychrotolerant microalgae culture collection, and to determine the general biotechnological properties of the isolated strains. The project is funded by TUBİTAK (Grant# 119Y399).
