Osmotic Imbalance, Cytoplasm Acidification and Oxidative Stress Induction Support the High Toxicity of Chloride in Acidophilic Bacteria

open access: yesFrontiers in Microbiology, 2019
In acidophilic microorganisms, anions like chloride have higher toxicity than their neutrophilic counterparts. In addition to the osmotic imbalance, chloride can also induce acidification of the cytoplasm.

Bioavailability of soil organic carbon and Fe as influenced by forestry practices in a subtropical coastal catchment [PDF]

open access: yes, 2010
Potential impacts of plantation forestry practices on soil organic carbon and Fe available to microorganisms were investigated in a subtropical coastal catchment. The impacts of harvesting or replanting were largely limited to the soil top layer (0–10 cm

The pio Operon Is Essential for Phototrophic Fe(II) Oxidation in Rhodopseudomonas palustris TIE-1 [PDF]

open access: yes, 2006
Phototrophic Fe(II)-oxidizing bacteria couple the oxidation of ferrous iron [Fe(II)] to reductive CO2 fixation by using light energy, but until recently, little has been understood about the molecular basis for this process. Here we report the discovery,

Fasciola hepatica‐Derived Proteins Shield the Heart From Type 2 Myocardial Infarction in Rats by Modulating Oxidative Stress and Inflammatory Imbalance: Insights Relevant to the Hygiene Hypothesis

open access: yesOxidative Medicine and Cellular Longevity, Volume 2026, Issue 1, 2026.
Myocardial infarction (MI) remains a leading cause of mortality worldwide, with type 2 MI (T2MI) carrying a worse prognosis than type 1 MI (T1MI). The hygiene hypothesis suggests that reduced microbial exposure in sanitized environments contributes to immune dysregulation and inflammation‐related diseases.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Microbial Extremophiles in Evolutionary Aspect [PDF]

open access: yes, 2007
The microflora of the cryosphere of planet Earth provides the best analogs for life forms that might be found in the permafrost or polar ice caps of Mars, near the surface of the cometary nuclei, or in the liquid water beneath the ice crusts of icy moons

Unraveling the oral microbiome's role in Alzheimer's disease: From pathophysiology to therapeutic potential

open access: yesAlzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract Oral dysbiosis contributes to Alzheimer's disease (AD) by promoting neuroinflammation. Pathobionts such as Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum release virulence factors that induce amyloid beta aggregation and tau hyperphosphorylation, while the loss of commensals like Streptococcus salivarius and ...

Soil Microbial Responses to Artificial CO2 Leakage in Controlled Field Experiments in South Korea

open access: yesGreenhouse Gases: Science and Technology, Volume 15, Issue 6, Page 779-791, December 2025.
ABSTRACT The potential environmental impacts of CO2 leakage from carbon capture and storage (CCS) sites remain a critical concern for the long‐term viability of CCS technologies. Soil microbial communities, which regulate essential biogeochemical processes, are particularly sensitive to changes in soil CO2 concentrations.
