Diverse mechanisms for pH sensing and cytoplasmic pH homeostasis enable most bacteria
to tolerate or grow at external pH values that are outside the cytoplasmic pH range they must …

Iron is a ubiquitous element in the universe. Ferrous iron (Fe (II)) was abundant in the
primordial ocean until the oxygenation of the Earth's atmosphere led to its widespread …

Background Acidithiobacillus ferrooxidans is a major participant in consortia of
microorganisms used for the industrial recovery of copper (bioleaching or biomining). It is a …

Background Acidithiobacillus ferrooxidans gains energy from the oxidation of ferrous iron
and various reduced inorganic sulfur compounds at very acidic pH. Although an initial model …

The energy-converting redox enzymes perform productive reactions efficiently despite the
involvement of high energy intermediates in their catalytic cycles. This is achieved by kinetic …

The widely distributed Acidithiobacillus ferrooxidans (A. ferrooxidans) lives in extremely
acidic conditions by fixing CO 2 and nitrogen, and by obtaining energy from Fe 2+ oxidation …

The iron respiratory chain of the acidophilic bacterium Acidithiobacillus ferrooxidans
involves various metalloenzymes. Here we demonstrate that the oxygen reduction pathway …

Genome analyses and the resolution of three–dimensional structures have provided
evidence in recent years for hitherto unexpected family relationships between redox proteins …

Acidithiobacillus ferrooxidans is a gram-negative, autotrophic and rod-shaped bacterium. It
can gain energy through the oxidation of Fe (II) and reduced inorganic sulfur compounds for …

Neutrophilic microaerophilic iron-oxidizing bacteria (FeOB) are thought to play a significant
role in cycling of carbon, iron and associated elements in both freshwater and marine iron …
