Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Biofertilzers with natural phosphate, sulphur and Acidithiobacillus in a siol with low available-P

Scientia Agricola, 2003
The production of mineral fertilizers is a expensive process, since it requires high energy consumption, and cannot be produced by small farmers. Laboratory assays were conducted to produce P-biofertilizers from natural phosphate (B5, B10, B15, B20 ...

Unveiling the Bioleaching Versatility of Acidithiobacillus ferrooxidans

Microorganisms
Acidithiobacillus ferrooxidans is a Gram-negative bacterium that thrives in extreme acidic conditions. It has emerged as a key player in biomining and bioleaching technologies thanks to its unique ability to mobilize a wide spectrum of elements, such as Li, P, V, Cr, Fe, Ni, Cu, Zn, Ga, As, Mo, W, Pb, U, and its role in ferrous iron oxidation and ...

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Effect of Introduction of Exogenous Strain Acidithiobacillus thiooxidans A01 on Structure and Function of Adsorbed and Planktonic Microbial Consortia During Bioleaching of Low-Grade Copper Sulfide

Frontiers in Microbiology, 2020
The introduction of Acidithiobacillus thiooxidans A01 strengthens the positive interactions between physiologically distinct microorganisms and enhances the bioleaching ability of the consortium. However, the effect of introducing an exogenous strain, A.

Acidithiobacillus ferrooxidans's comprehensive model driven analysis of the electron transfer metabolism and synthetic strain design for biomining applications

Metabolic Engineering Communications, 2016
Acidithiobacillus ferrooxidans is a gram-negative chemolithoautotrophic γ-proteobacterium. It typically grows at an external pH of 2 using the oxidation of ferrous ions by oxygen, producing ferric ions and water, while fixing carbon dioxide from the ...

Comparative genomics in acid mine drainage biofilm communities reveals metabolic and structural differentiation of co-occurring archaea [PDF]

, 2016
Background Metal sulfide mineral dissolution during bioleaching and acid mine drainage (AMD) formation creates an environment that is inhospitable to most life. Despite dominance by a small number of bacteria, AMD microbial biofilm communities contain a
