Effects of Salinity and Temperature on the Flexibility and Function of a Polyextremophilic Enzyme

International Journal of Molecular Sciences, 2022
The polyextremophilic β-galactosidase enzyme of the haloarchaeon Halorubrum lacusprofundi functions in extremely cold and hypersaline conditions. To better understand the basis of polyextremophilic activity, the enzyme was studied using steady-state kinetics and molecular dynamics at temperatures ranging from 10 °C to 50 °C and salt concentrations from

Potential influence of microorganisms on the corrosion of carbon steel in the French high‐level long‐lived radioactive waste disposal context at 80°C

Materials and Corrosion, Volume 74, Issue 11-12, Page 1795-1810, November‐December 2023., 2023
Microbially influenced corrosion (MIC) risk is assessed in the context of the French high‐level radioactive waste disposal. Experiments were carried out in different media with complementary microorganisms from underground research laboratory and culture collection centers.

Geomicrobiology of the Rincon de Parangueo maar crater: Exploring the link between an evolving extreme environment and its potential metabolic diversity

Freshwater Biology, Volume 68, Issue 11, Page 1818-1838, November 2023., 2023
Abstract Rincon de Parangueo (RP) is a Quaternary maar crater located in the Michoacan‐Guanajuato Volcanic Field in central Mexico. Like other volcanic craters in the region, the central part was occupied by an endorheic lacustrine system. As a consequence of extensive groundwater extraction, the perennial lake started a gradual desiccation process and

Polyextremophile engineering: a review of organisms that push the limits of life. [PDF]

Front Microbiol
Nature exhibits an enormous diversity of organisms that thrive in extreme environments. From snow algae that reproduce at sub-zero temperatures to radiotrophic fungi that thrive in nuclear radiation at Chernobyl, extreme organisms raise many questions about the limits of life. Is there any environment where life could not “find a way”?

Multimodal imaging reveals a small subpopulation of Deinococcus radiodurans exhibiting correlated low superoxide radical levels with extraordinary silver ion metabolism

Natural Sciences, Volume 2, Issue 4, October 2022., 2022
Multi‐modal imaging reveals a subpopulation of Deinococcus radiodurans exhibiting extraordinary heavy metal metabolism and correlated low reactive oxygen species levels. Abstract A polyvalent strategy has recently been assumed to be adopted by Deinococcus radiodurans that can generate various resistance against many different detrimental sources of ...

Astrobiology of life on Earth

Environmental Microbiology, Volume 23, Issue 7, Page 3335-3344, July 2021., 2021
Summary Astrobiology is mistakenly regarded by some as a field confined to studies of life beyond Earth. Here, we consider life on Earth through an astrobiological lens. Whereas classical studies of microbiology historically focused on various anthropocentric sub‐fields (such as fermented foods or commensals and pathogens of crop plants, livestock and ...

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 ...

Systems biology of cold adaptation in the polyextremophilic red alga Galdieria sulphuraria [PDF]

Frontiers in Microbiology, 2019
Abstract Rapid fluctuation of environmental conditions can impose severe stress upon living organisms. Surviving such episodes of stress requires a rapid acclimation response, e.g., by transcriptional and post-transcriptional mechanisms.

Protease Production from Polyextremophilic Bacteria

International Journal of Current Microbiology and Applied Sciences, 2016
A B S T R A C T Extremophilic organisms which are capable of surviving in two different extreme environmental conditions simultaneously are known as polyextremophiles. These organisms are known to be potent producers of bioactive compounds namely enzymes such as proteases which are rapidly used in the growing industrial sector uses such as in the ...
