Isolation of the Thiobacillus ferrooxidans ntrBC genes using a T. ferrooxidans nifH-lacZ fusion [PDF]
An agar plating technique was developed in which the activation of expression of a Thiobacillus ferrooxidans nifH-lacZ gene fusion was used to isolate the ntrBC genes from a T. ferrooxidans gene library. An Escherichia coli ntrC mutant containing the nifH-lacZ fusion was transformed and plated on a low-nitrogen medium so that on flooding with ONPG, the

Ultrasound enhances the recycling process and mechanism of lithium from spent LiFePO4 batteries by Acidithiobacillus ferrooxidans [PDF]
In this study, the ability of Acidithiobacillus ferrooxidans to oxidize Fe2+ to Fe3+ and recover battery black powder was investigated, establishing a system for leaching decommissioned lithium iron phosphate battery black powder from A.

Current understanding of electroautotrophy and its relevance in astrobiology-related research. [PDF]
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 ...

Bioleaching Microbial Community Metabolism and Composition Driven by Copper Sulphide Mineral Type. [PDF]
Bioleaching is a microbially mediated green technology for the recovery of metals from ore. Here, microbial consortia from a copper bioleaching column in Cyprus were cultivated on chalcopyrite (CuFeS2) and then sub‐cultured on chalcocite (Cu2S) and chalcopyrite to investigate how mineral type and surface chemistry influence microbial community ...

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression. [PDF]
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 ...

Unveiling the Bioleaching Versatility of Acidithiobacillus ferrooxidans. [PDF]
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 ...
