Metagenomic Investigation of a Low Diversity, High Salinity Offshore Oil Reservoir

Microorganisms, 2021
Oil reservoirs can represent extreme environments for microbial life due to low water availability, high salinity, high pressure and naturally occurring radionuclides.

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

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 ...

Comparative Genome Analysis of Three Halobacillus Strains Isolated From Saline Environments Reveal Potential Salt Tolerance and Algicidal Mechanisms. [PDF]

Environ Microbiol Rep
Following the previous complete genome analysis, this research provides the function of new Halobacillus species. Three strains were identified: Halobacillus shinanisalinarum sp. nov. SSTM10‐2T, Halobacillus salinarum sp. nov. SSBR10‐3T, and Halobacillus amylolyticus sp. nov. SSHM10‐5T.
