The Genetic Determinants of Extreme UV Radiation and Desiccation Tolerance in a Bacterium Recovered from the Stratosphere

by Keith Cowing

Microbes that survive transport to and in the stratosphere endure extremes of low temperature, atmospheric pressure, and relative humidity, as well as high fluxes in ultraviolet radiation (UVR).

Near Space Microbiology: Curtobacterium aetherium Discovered In Earth’s Stratosphere

by Keith Cowing

Although the high-altitude limit for microbial survival in the Earth–atmosphere system has remained a scientific curiosity and topic of study, the ecological significance of long-distance microbial dispersal in the atmosphere […]
