Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]

, 2019
Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

When biodiversity preservation meets biotechnology: The challenge of developing synthetic microbiota for resilient sustainable crop production

Journal of Sustainable Agriculture and Environment, Volume 2, Issue 1, Page 5-15, March 2023., 2023
Abstract Agriculture needs to develop novel strategies and practices to meet the increasing global food demand, in an ecological and economical sustainable framework. The plant‐associated microbiota is gaining increasing attention as part of these strategies since it strongly contributes to plant health, nutrition, and resilience to environmental ...

Responses to the Hydrostatic Pressure of Surface and Subsurface Strains of Pseudothermotoga elfii Revealing the Piezophilic Nature of the Strain Originating From an Oil-Producing Well

Frontiers in Microbiology, 2020
Microorganisms living in deep-oil reservoirs face extreme conditions of elevated temperature and hydrostatic pressure. Within these microbial communities, members of the order Thermotogales are predominant.

Adaptations to high pressure of Nautilia sp. strain PV‐1, a piezophilic Campylobacterium (aka Epsilonproteobacterium) isolated from a deep‐sea hydrothermal vent

Environmental Microbiology, Volume 24, Issue 12, Page 6164-6183, December 2022., 2022
Abstract Physiological and gene expression studies of deep‐sea bacteria under pressure conditions similar to those experienced in their natural habitat are critical for understanding growth kinetics and metabolic adaptations to in situ conditions. The Campylobacterium (aka Epsilonproteobacterium) Nautilia sp.

Analyzing structural features of proteins from deep‐sea organisms

Proteins: Structure, Function, and Bioinformatics, Volume 90, Issue 8, Page 1521-1537, August 2022., 2022
Abstract Protein adaptations to extreme environmental conditions are drivers in biotechnological process optimization and essential to unravel the molecular limits of life. Most proteins with such desirable adaptations are found in extremophilic organisms inhabiting extreme environments. The deep sea is such an environment and a promising resource that

Transcriptomics reveal several gene expression patterns in the piezophile Desulfovibrio hydrothermalis in response to hydrostatic pressure. [PDF]

PLoS ONE, 2014
RNA-seq was used to study the response of Desulfovibrio hydrothermalis, isolated from a deep-sea hydrothermal chimney on the East-Pacific Rise at a depth of 2,600 m, to various hydrostatic pressure growth conditions.

Pressure effects on sulfur‐oxidizing activity of Thiobacillus thioparus

Environmental Microbiology Reports, Volume 13, Issue 2, Page 169-175, April 2021., 2021
Abstract Carbon capture and storage technologies are crucial for reducing carbon emission from power plants as a response to global climate change. The CarbFix project (Iceland) aims at examining the geochemical response of injected CO2 into subsurface reservoirs.

Structure and Function of Piezophilic Hyperthermophilic Pyrococcus yayanosii pApase [PDF]

International Journal of Molecular Sciences, 2021
3’-Phosphoadenosine 5’-monophosphate (pAp) is a byproduct of sulfate assimilation and coenzyme A metabolism. pAp can inhibit the activity of 3′-phosphoadenosine 5′-phosphosulfate (PAPS) reductase and sulfotransferase and regulate gene expression under stress conditions by inhibiting XRN family of exoribonucleases.

Exploring Enzymatic Activity in Multiparameter Space: Cosolvents, Macromolecular Crowders and Pressure

ChemSystemsChem, Volume 3, Issue 2, March 2021., 2021
Mimicking the cellular milieu of deep‐sea piezophiles, the combined effect of crowding agents, osmolytes and pressure on the enzymatic activity of α‐chymotrypsin has been studied. Addition of the deep‐sea osmolyte trimethylamine‐N‐oxide (TMAO) displays by far the most positive effect on the catalytic efficiency, which is even markedly enhanced at high ...
