Geyserite in Hot-Spring Siliceous Sinter: Window on Earth’s Hottest Terrestrial (Paleo)environment and its Extreme Life [PDF]

, 2015
International audienceSiliceous hot-spring deposits, or sinters, typically form in active, terrestrial (on land), volcanic terrains where magmatically heated waters circulating through the shallow crust emerge at the Earth's surface as silica-charged ...

Microbe‐Mediated Extracellular and Intracellular Mineralization: Environmental, Industrial, and Biotechnological Applications

Advanced Materials, Volume 32, Issue 22, June 4, 2020., 2020
Different types of biomineralization, including calcification, silicification, iron, carbon, nitrogen, and phosphorus mineralization, which are mediated by algae, bacteria, fungi, and viruses, are summarized. The mechanisms of extracellular and intracellular microbe‐mediated mineralization, as well as their environmental, industrial, and ...

Prospects for harnessing biocide resistance for bioremediation and detoxification [PDF]

, 2018
Prokaryotes in natural environments respond rapidly to high concentrations of chemicals and physical stresses. Exposure to anthropogenic toxic substancessuch as oil, chlorinated solvents, or antibioticsfavors the evolution of resistant phenotypes, some ...

Confidence of Life Detection: The Problem of Unconceived Alternatives [PDF]

, 2023
Potential biosignatures that offer the promise of extraterrestrial life (past or present) are to be expected in the coming years and decades, whether from within our own solar system, from an exoplanet atmosphere, or otherwise.

Synthesis of salt-stable fluorescent nanoparticles (quantum dots) by polyextremophile halophilic bacteria [PDF]

Scientific Reports, 2019
AbstractHere we report the biological synthesis of CdS fluorescent nanoparticles (Quantum Dots, QDs) by polyextremophile halophilic bacteria isolated from Atacama Salt Flat (Chile), Uyuni Salt Flat (Bolivia) and the Dead Sea (Israel). In particular, a Halobacillus sp. DS2, a strain presenting high resistance to NaCl (3–22%), acidic pH (1–4) and cadmium

In vitro biosynthesis of Ag, Au and Te-containing nanostructures by Exiguobacterium cell-free extracts

BMC Biotechnology, 2020
Background The bacterial genus Exiguobacterium includes several species that inhabit environments with a wide range of temperature, salinity, and pH. This is why the microorganisms from this genus are known generically as polyextremophiles.

Anion-type modulates the effect of salt stress on saline lake bacteria [PDF]

, 2022
Beside sodium chloride, inland saline aquatic systems often contain other anions than chloride such as hydrogen carbonate and sulfate. Our understanding of the biological effects of salt composition diversity is limited; therefore, the aim of this study ...

Prevalent pH Controls the Capacity of Galdieria maxima to Use Ammonia and Nitrate as a Nitrogen Source [PDF]

, 2020
Galdieria maxima is a polyextremophilic alga capable of diverse metabolic processes. Ammonia is widely used in culture media typical of laboratory growth. Recent reports that this species can grow on wastes promote the concept that G.

An Antarctic Extreme Halophile and Its Polyextremophilic Enzyme: Effects of Perchlorate Salts [PDF]

Astrobiology, 2018
Effects of perchlorate salts prevalent on the surface of Mars are of significant interest to astrobiology from the perspective of potential life on the Red Planet. Halorubrum lacusprofundi, a cold-adapted halophilic Antarctic archaeon, was able to grow anaerobically on 0.04 M concentration of perchlorate.
