The impact of gravitational sedimentation on the sulfate-reducing bacterium biofilms formation that induced biocorrosion of X80 steel

npj Materials Degradation
In this study, X80 steel square specimens were immersed in a culture of sulfate-reducing bacteria (SRB), Desulfovibrio vulgaris, and the impact of gravity sedimentation on biofilm formation was investigated in three different directions (upward, sideward,

Demonstration of the Role of Both a Ttr and a Psr Homologue Enzymes in the Respiration of Tetrathionate by an Environmental Bacterium Shewanella sp. ANA‐3

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Using a combination of deletion mutants' construction, phenotyping of these mutants and complementary biochemical analyses, we established that the environmental Shewanella sp. ANA‐3 is using both the tetrathionate reductase Ttr and the polysulfide reductase Psr to respire tetrathionate.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, Volume 13, Issue 10, 18 February 2026.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Iron Sulfides Produced by Thermococcales: An Iron Detoxification Mechanism

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Thermococcales, archaea from hydrothermal vents, promote iron sulfide precipitation, enabling survival in iron‐rich environments. Some cells become encrusted in pyrite and do not survive mineralization, while surviving cells activate metal detoxification genes. This biomineralization process allows the population to withstand toxic iron concentrations,
