Microorganisms with the ability to survive high doses of radiation are known as radiation-
resistant extremophiles. This study attempts to demonstrate the diversity of microorganisms …

Isolation of most ultraviolet B (UV-B)-resistant culturable bacteria that occur in the habitat of
Laguna Azul, a high-altitude wetland [4554 m above sea level (asl)] from the Northwestern …

Among extremophiles, microorganisms resistant to ultraviolet radiation (UVR) have been
known to produce a variety of metabolites (ie, extremolytes). We hypothesized that natural …

Organisms in hot, arid environment have to cope with adverse life conditions such as
desiccation, temperature and lack of nutrients. The phylogenetic diversity of ultra-violet (UV) …

The high UV radiation and scarcity of liquid water in desert areas make these regions
among the most challenging environments for life. Here we studied the multitolerant …

Soil microbial communities are important contributors to the desert ecosystem. Top soil is
vital for biological activity but is often exposed to large amounts of DNA damaging ultraviolet …

UV irradiation is known to cause harmful effects on microorganisms. As the result,
microorganisms have developed protection against exposure to harmful UV irradiation. We …

Desiccation resistance and a high intracellular Mn/Fe ratio contribute to ionizing radiation
resistance of Deinococcus radiodurans. We hypothesized that this was a general …

A rich diversity of radiation-resistant (Rr) and desiccation-resistant (Dr) bacteria has been
found in arid habitats of the world. Evidence from scientific research has linked their origin to …

Six bacterial isolates from the US DOE Subsurface Science Program and three references
bacteria were tested for resistance to UV light and gamma radiation. The subsurface isolates …
