Abstract

Antarctica is known by the predominance of extreme characteristics, such as climate, habitat, and biogeography. Life presents in the continent is singular due to the conditions they are exposed to, which they had to adapt by the developing of mechanisms that reflect all the environmental adversity. Nowadays, under the climate changes, the Antarctic continent shows geographic disturbance, specially seen in the Collins glacier, situated in the King George Island. As a result of the glacier retreat, the microbial life is being exposed, unfolding new scientific possibilities. The present work is part of the projects FAPESP 2013/19486-0 and PROANTAR/CNPq MICROSFERA and has as the main goal to study the yeasts' diversity from different samples of Collins glacier retreat soil (Fildes Peninsula, King George Island). In addition, studies related to UV radiation resistance will be developed. The conduction of the present study may result in the discovery of new species and biotechnological innovations under the scope of ultraviolet radiation resistance. (AU)
