Coordinators: Milton Costa and Nuno Empadinhas

Summary
Life is everywhere, even in the most extreme environments that one can imagine. How can organisms survive and be metabolically active in the extremely cold environments from Antarctida with subfreezing temperatures? How do microbial life forms thrive on toxic levels of sulfides and heavy metals above magma plumes with extremely high temperatures? How is it possible that organisms exist in the complete absence of light at Km depths in the ocean, buried deep within land masses or in the hot, UV-exposed soils from extremely arid deserts?
The secrets of Life in Extreme Environments are only now beginning to be unravelled and this course provides a general insight into the subject. Extant prokaryotes exhibit an extraordinary range of metabolic versatility that continues to expand as new species are isolated from extreme environments. The course will cover the current knowledge of prokaryotic biodiversity in some of these environments, and explore some of the strategies used by those microorganisms to endure and adapt to such conditions.
The biotechnological impact and the biomedical potential of extremophiles and their products will also be addressed.
