Effects of increasing hydrostatic pressures on marine microbial enzymatic activities [PDF]

Limnology and Oceanography, Volume 70, Issue 9, Page 2632-2644, September 2025.
High hydrostatic pressure is characteristic of the deep ocean and is presumed to influence microbial functions and viability. However, marine microbial processes are typically measured only at atmospheric pressure (0.1 MPa), limiting our understanding of

The secretome of Thermococcus barophilus in the presence of carbohydrates and the potential role of the TrmBL4 regulator. [PDF]

Environ Microbiol Rep, 2023
The secretome of Thermococcus barophilus was explored in the light of sugar metabolism (maltose, maltodextrin and pectin). The expression of certain secreted proteins is directly dependent on the sugar regulator TrmBL4, as is the ABC maltose/maltodextrin transporter (MD system), but not the trehalose/maltose transport system (TM system).

Enzymes from piezophiles. [PDF]

Semin Cell Dev Biol, 2018
The discovery of microbial communities in extreme conditions that would seem hostile to life leads to the question of how the molecules making up these microbes can maintain their structure and function. While microbes that live under extremes of temperature have been heavily studied, those that live under extremes of pressure, or "piezophiles", are ...

Biological functions at high pressure: transcriptome response of Shewanella oneidensis MR-1 to hydrostatic pressure relevant to Titan and other icy ocean worlds. [PDF]

Front Microbiol
High hydrostatic pressure (HHP) is a key driver of life's evolution and diversification on Earth. Icy moons such as Titan, Europa, and Enceladus harbor potentially habitable high-pressure environments within their subsurface oceans. Titan, in particular,

Microbiomes of Hadal Fishes across Trench Habitats Contain Similar Taxa and Known Piezophiles

mSphere, 2022
Hadal snailfishes are the deepest-living fishes in the ocean, inhabiting trenches from depths of ∼6,000 to 8,000 m. While the microbial communities in trench environments have begun to be characterized, the microbes associated with hadal megafauna remain

A molecular perspective on the limits of life: Enzymes under pressure [PDF]

, 2016
From a purely operational standpoint, the existence of microbes that can grow under extreme conditions, or "extremophiles", leads to the question of how the molecules making up these microbes can maintain both their structure and function. While microbes

Cross-Stress Adaptation in a Piezophilic and Hyperthermophilic Archaeon From Deep Sea Hydrothermal Vent

Frontiers in Microbiology, 2020
Hyperthermophiles, living in environments above 80°C and usually coupling with multi-extreme environmental stresses, have drawn great attention due to their application potential in biotechnology and being the primitive extant forms of life.

Effects of hydrostatic pressure on growth and luminescence of a moderately-piezophilic luminous bacteria Photobacterium phosphoreum ANT-2200. [PDF]

PLoS ONE, 2013
Bacterial bioluminescence is commonly found in the deep sea and depends on environmental conditions. Photobacterium phosphoreum ANT-2200 has been isolated from the NW Mediterranean Sea at 2200-m depth (in situ temperature of 13°C) close to the ANTARES ...

Effects of chaotropic salts on global proteome stability in halophilic archaea: Implications for life signatures on Mars

Environmental Microbiology, Volume 25, Issue 11, Page 2216-2230, November 2023., 2023
Abstract Halophilic archaea thriving in hypersaline environments, such as salt lakes, offer models for putative life in extraterrestrial brines such as those found on Mars. However, little is known about the effect of the chaotropic salts that could be found in such brines, such as MgCl2, CaCl2 and (per)chlorate salts, on complex biological samples ...
