Geographical Distribution and Biotechnological Potential of Cultivable Filamentous Fungi in Soils of Fildes Bay (Antarctica)
In the Antarctic territory, only 0.35% of its surface is ice-free. Fildes Bay is one of these notable areas, due to its geographical location and better environmental conditions when compared to the Antarctic continent. Fildes Bay is an ideal site for studying microorganisms, such as filamentous fun...
