The formation of ice particles in the Earth's atmosphere strongly affects the properties of
clouds and their impact on climate. Despite the importance of ice formation in determining …

Atmospheric aerosol particles of biological origin are a very diverse group of biological
materials and structures, including microorganisms, dispersal units, fragments and …

Understanding how antibiotic resistance emerges and evolves in natural habitats is critical
for predicting and mitigating antibiotic resistance in the context of global change. Bacteria …

Life can be stressful. One way to deal with stress is to simply wait it out. Microbes do this by
entering a state of reduced activity and increased resistance commonly called 'dormancy' …

Cold environments represent the majority of the biosphere on Earth and have been
successfully colonized by psychrophilic microorganisms that are able to thrive at low …

Planococcus halocryophilus strain Or1, isolated from high Arctic permafrost, grows and
divides at− 15° C, the lowest temperature demonstrated to date, and is metabolically active …

Although bacteria are ubiquitous in the near-surface atmosphere, the temporal dynamics of
airborne bacterial communities have not been well-studied. We examined seasonal shifts in …

Bacteria and fungi are ubiquitous in the atmosphere. The diversity and abundance of
airborne microbes may be strongly influenced by atmospheric conditions or even influence …

Based on long-term systematic sampling, information is currently limited regarding the
impacts of different air pollution levels on variations of bacteria, fungi and ammonia …

Bacteria of the genus Exiguobacterium are low G+ C, Gram-positive facultative anaerobes
that have been repeatedly isolated from ancient Siberian permafrost. In addition …
