Resumen:
Antarctica offers a range of extreme climatic conditions such as low
temperatures, high solar radiation, low nutrient
availability and constitutes one of the harshest environments Earth. Despite of
that, it has been successfully colonized by ?cold-loving? fungi, who play a key
role in decomposition cycles in cold ecosystems. However, yeast´s ecological
role on the nutrient or organic matter recycling/mineralization remains highly
fragmentary.
The aim of this work was to study the yeast microbiota in samples
collected on 25 de Mayo/King George Island, in the scope of their ability to
degrade polyphenolic substrates such as lignin and humic substances.
