Microbial Populations in Antarctic Permafrost
Members of NAI’s Michigan State University Alumni Team are part of an international team of scientists characterizing the microbial populations in Antarctic permafrost soils. Based on multiple samples, they describe the presence of diverse populations of both aerobic and anaerobic bacteria, cyanobacteria, green algae, yeasts, and fungi. Based on the documented ages of the permafrost regions—perhaps more than 5 million years old—these findings represent the oldest viable microorganisms discovered in permafrost on Earth. Their paper appears in the April issue of Astrobiology.
