Antarctica has been successfully colonized by microorganisms despite presenting adverse conditions
for life such as low temperatures, high solar radiation, low nutrient availability and dryness. Although these
“cold-loving” microorganisms are recognized as primarily responsible for nutrient and organic matter recycling/
mineralization, the yeasts, in particular, remain poorly characterized and understood. The aim of this work was to
study the yeast microbiota in soil and water samples collected on King George Island.
