Biogeochemical characterization of four depleted gas reservoirs for conversion into underground hydrogen storage

Environmental Microbiology, Volume 25, Issue 12, Page 3683-3702, December 2023., 2023
Depleted gas reservoirs are a promising underground hydrogen storage (UHS) option. This study is the first microbiological characterization of four Italian depleted reservoirs in the perspective of UHS. Our approach integrates hydrochemical analysis and metagenomic characterization, based on 16S rRNA and functional genes, with predictive functional ...

Detection of dsrAB operon expression in Desulfotalea psychrophila cells subjected to simulated Martian conditions of temperature and regolith's sulphate minerals composition

International Journal of Astrobiology, 2023
AbstractDiscoveries of transient liquid water in the Martian polar caps and the presence of liquid lakes and subsurface oceans in icy satellites have increased the interest of scientists in the capabilities of terrestrial extremophiles to grow and remain metabolically active in these extreme environments.

A metagenomic view of novel microbial and metabolic diversity found within the deep terrestrial biosphere at DeMMO: A microbial observatory in South Dakota, USA

Environmental Microbiology, Volume 25, Issue 12, Page 3719-3737, December 2023., 2023
This study presents a large geochemically informed genomic dataset from a deep mine environment. We assembled hundreds of metagenome‐derived genomes, many from uncultivated groups, gaining insight into potential microbial metabolisms that in subsurface fluids and how these microbes interface with their biogeochemical environments at these extremes ...

Sulfate-reducing microorganisms in wetlands – fameless actors in carbon cycling and climate change

Frontiers in Microbiology, 2012
Freshwater wetlands are a major source of the greenhouse gas methane but at the same time can function as carbon sink. Their response to global warming and environmental pollution is one of the largest unknowns in the upcoming decades to centuries.

Metagenomic and metatranscriptomic insights into sulfate-reducing bacteria in a revegetated acidic mine wasteland

npj Biofilms and Microbiomes, 2022
The widespread occurrence of sulfate-reducing microorganisms (SRMs) in temporarily oxic/hypoxic aquatic environments indicates an intriguing possibility that SRMs can prevail in constantly oxic/hypoxic terrestrial sulfate-rich environments.

The Active Sulfate-Reducing Microbial Community in Littoral Sediment of Oligotrophic Lake Constance

Frontiers in Microbiology, 2019
Active sulfate-reducing microorganisms (SRM) in freshwater sediments are under-examined, despite the well-documented cryptic sulfur cycle occurring in these low-sulfate habitats.

pH mediated assemblage of carbon, nitrogen, and sulfur related microbial communities in petroleum reservoirs

Frontiers in Microbiology, 2022
Microorganisms are the core drivers of biogeochemistry processes in petroleum reservoirs and have been widely used to enhance petroleum recovery. However, systematic information about the microbial communities related to the C-N-S cycle in petroleum ...

Activity and phylogenetic diversity of sulfate-reducing microorganisms in low-temperature subsurface fluids within the upper oceanic crust

Frontiers in Microbiology, 2015
The basaltic ocean crust is the largest aquifer system on Earth, yet the rates of biological activity in this environment are unknown. Low-temperature (
