Polyextremophiles: Summary and Conclusions
Cellular Origin and Life in Extreme Habitats, 2013The search for extraterrestrial life is encouraged by a comparison between organisms living in severe environmental conditions on Earth and the physical and chemical conditions that exist on some Solar System bodies. Astrobiology raises the possibility of life elsewhere in the Solar System (cf., the chapter by Joseph Seckbach – “Life on the Edge and ...

Polyextremophiles and the Constraints for Terrestrial Habitability
Cellular Origin and Life in Extreme Habitats, 2013Life on Earth occupies a multidimensional niche space that has yet to be fully described. The niche space of terrestrial life is knowable, and thus, it guides the search for hypothesized life. Since terrestrial life is constrained by its organic carbon foundation and requirement for water as a solvent, extremes in such environmental parameters as ...

Marine Polyextremophiles and Their Biotechnological Applications
2017This chapter describes the versatility of marine microorganisms. They have inherent ability to grow and thrive under polyextremes. The bioactive compounds such as hydrolases, unique pigments, alkaloids, peptides, colored antibiotics, exopolysaccharides, siderophores, ectoine, and proteins produced and released under stressful conditions have potential ...

Life on the Edge and Astrobiology: Who Is Who in the Polyextremophiles World?
Cellular Origin and Life in Extreme Habitats, 2013Life exists in almost every ecological niche on Earth, and the majority of living organisms thrive in “normal” or “common” conditions. These are the environments that we are familiar with from our daily life. The organisms distributed under those conditions are at moderate temperature (5 to ~40 °C), 1 atm sea level pressure, with our known gas ...

Stress tolerance in a polyextremophile: the southernmost insect
Canadian Journal of Zoology, 2015Since biotic interactions within the simple terrestrial communities on the Antarctic Peninsula are limited compared with tropical and temperate regions, survival is largely dictated by the numerous abiotic challenges. Our research focuses on adaptations to environmental stresses experienced by the Antarctic midge (Belgica antarctica Jacobs, 1900), the
