Microbial iron management mechanisms in extremely acidic environments: comparative genomics evidence for diversity and versatility

BMC Microbiology, 2008
Background Iron is an essential nutrient but can be toxic at high intracellular concentrations and organisms have evolved tightly regulated mechanisms for iron uptake and homeostasis.

Characterization of an OmpA-like outer membrane protein of the acidophilic iron-oxidizing bacterium, Acidithiobacillus ferrooxidans [PDF]

, 2011
An OmpA family protein (FopA) previously reported as one of the major outer membrane proteins of an acidophilic iron-oxidizing bacterium Acidithiobacillus ferrooxidans was characterized with emphasis on the modification by heat and the interaction with ...

Fe(III) bioreduction kinetics in anaerobic batch and continuous stirred tank reactors with acidophilic bacteria relevant for bioleaching of limonitic laterites

Frontiers in Microbiology
In the framework of the H2020 project CROCODILE, the recovery of Co from oxidized ores by reductive bioleaching has been studied. The objective was to reduce Fe(III) to Fe(II) to enhance the dissolution of Co from New-Caledonian limonitic laterites ...

Bioleaching of Copper Sulfide Ores: From Microbial Mechanisms to Industrial Applications

Separations
The global energy transition and rapid electrification are driving increased demand for copper. However, conventional pyrometallurgical and hydrometallurgical extraction routes are increasingly challenged by declining ore grades and stricter ...

QS molecules change the planktonic/mineral subpopulations distribution of moderately thermophilic leaching bacteria in pyrite and decrease leaching in chalcopyrite

Frontiers in Microbiology
Biomining is a sustainable alternative to conventional mineral processing that uses acidophilic microorganisms to catalyze the extraction of valuable metals from sulfide minerals.

Phosphorus liberation by aquatic microorganisms [PDF]

, 2009
The conventionally accepted route for cycling of inorganic phosphorus (P) was previously thought to be the long-term processes of abiotic physical and chemical weathering and subsequent physical exchange reactions with minerals.

Inhibition of cell lysis to acidophilic microorganisms and microbial strategies to alleviate this

, 2016
During my degree’s final graduation project was investigated factors that inhibit acidophilic iron oxidizer microorganisms. These microorganisms have the ability to oxidize the Fe2 + to Fe3 + and S to SO42- and are the main catalyst during bioleaching ...
