The pyruvate:ferredoxin oxidoreductase of the thermophilic acetogen, Thermoanaerobacter kivui

FEBS Open Bio, 2021
Pyruvate:ferredoxin oxidoreductase (PFOR) is a key enzyme in bacterial anaerobic metabolism. Since a low‐potential ferredoxin (Fd2−) is used as electron carrier, PFOR allows for hydrogen evolution during heterotrophic growth as well as pyruvate synthesis

MISS diversity from saline lakes of Brazilian Pantanal: Origin, potential of preservation and comparison with examples of the Ediacaran‐Cambrian shallow depositional settings

Sedimentology, EarlyView.
ABSTRACT One of the largest wetlands on Earth, the Brazilian Pantanal contains roughly 10 000 natural lakes, about 1000 of which are hypersaline. In these environmentally stressful settings, animal life struggles to survive, while cyanobacteria form extensive mats.

Communities that thrive in extreme conditions captured from a freshwater lake [PDF]

, 2016
Organisms that can grow in extreme conditions would be expected to be confined to extreme environments. However, we were able to capture highly productive communities of algae and bacteria capable of growing in acidic (pH 2), basic (pH 12) and saline (40

Geometry Controls Confined Water Dynamics in Lipidic Mesophases

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.
An archaeal‐inspired lipidic mesophase allows precise control of interfacial curvature and water‐channel connectivity. Combining structural, thermodynamic, and ultrafast spectroscopies, we reveal that curvature governs the structure and reorientation dynamics of confined water, establishing a molecular‐level link between topology and dynamics in soft ...

Evolutionary tinkering of the expression of PDF1s suggests their joint effect on zinc tolerance and the response to pathogen attack [PDF]

, 2014
Multigenic families of Plant Defensin type 1 (PDF1) have been described in several species, including the model plant Arabidopsis thaliana as well as zinc tolerant and hyperaccumulator A. halleri. In A.

Antimicrobial and Cytotoxic Activities of Biogenic Nanoparticles Produced by Cyanobacteria

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The article reviews the green synthesis of biogenic nanoparticles produced by cyanobacteria, highlighting their antimicrobial and cytotoxic properties. These nanoparticles, formed intra‐ or extracellularly, show activity against Gram‐positive and Gram‐negative bacteria as well as fungi and can induce apoptosis in tumor cells.

Bacillus pumilus isolated from sabkha rhizosphere ameliorates the behavior of the facultative halophyte Hordeum marinum when salt-challenged by improving nutrient uptake and soil health-related traits

Plant Stress
Plant growth-promoting rhizosphere bacteria (PGPR) are increasingly considered as highly efficient bioagents. They confer for instance better salt tolerance to host plants while improving soil enzyme activities and microbiome diversity, which are ...

Selective screening: isolation of fungal strains from contaminated soils in Austria

Die Bodenkultur, 2018
Microorganisms are potent contributors to maintaining a safe environment as they are able to degrade organic toxicants. For environmental applications, mostly bacteria are used while fungal strains have received less attention.
