Subsurface storage of hydrogen, eg in depleted oil and gas fields (DOGF), is suggested as a
means to overcome imbalances between supply and demand in the renewable energy …

Life at high salt concentrations is energetically expensive. The upper salt concentration limit
at which different dissimilatory processes occur in nature appears to be determined to a …

The underground hydrogen storage (UHS) in depleted hydrocarbon reservoirs, aquifers,
and saline caverns is regarded as a vital component of hydrogen economy value-chains …

Deep-sea ecosystems represent the largest biome of the global biosphere, but knowledge of
their biodiversity is still scant. The Mediterranean basin has been proposed as a hot spot of …

Highlights•Metagenomics permitted a better knowledge of the microbial diversity of
hypersaline habitats.•Cellular life in hypersaline habitats is dominated by prokaryotes …

Abstract Deep marine sediments (> 1mbsf) harbor~ 26% of microbial biomass and are the
largest reservoir of methane on Earth. Yet, the deep subsurface biosphere and controls on …

Halophiles are salt-loving organisms that inhabit hypersaline environments. They include
mainly prokaryotic and eukaryotic microorganisms with the capacity to balance the osmotic …

Profound biogeochemical responses of anoxic sediments to the fluctuation of dissolved
oxygen (DO) concentration in overlaying water are often observed, despite oxygen having a …

This study aimed at understanding how bacterial communities fluctuate and correlate with
wastewater treatment plant (WWTP) efficiency over a ten-month period. Illumina sequencing …

Summary The Red Sea harbours approximately 25 deep‐sea anoxic brine pools. They
constitute extremely unique and complex habitats with the conjugation of several extreme …
