microorganisms capable of oxidizing iron ore

Iron in Primeval Seas Rusted by Bacteria . 23, 2013 — Researchers from the University of Tübingen have been able to show for the first time how microorganisms contributed to the formation of the world's biggest iron ore deposits. The biggest known deposits or by the action of microaerophilic iron-oxidizing bacteria. But scientists are still debating at

Genomics, metagenomics and proteomics in biomining

The use of acidophilic, chemolithotrophic microorganisms capable of oxidizing iron and sulfur in industrial processes to recover metals from minerals containing copper, gold and uranium is a well established biotechnology with distinctive advantages over traditional mining. A consortium of different

Microorganisms pumping iron: anaerobic microbial iron

2006-10-1  Iron (Fe) has long been a recognized physiological requirement for life, yet for many microorganisms that persist in water, soils and sediments, its role extends

Oxidation and Reduction of Iron by Acidophilic Bacteria

2018-6-6  In addition to the well‐known autotrophic ferrous iron‐oxidizing organisms, new heterotrophic isolates have been described that are capable of oxidizing ferrous iron. Microorganisms can also play an important role in the reductive part of the iron cycle. Both heterotrophic and autotrophic organisms may also be involved in this process.

2016-9-15  The products sulfur and iron(II) can suffer a further microbial oxidation. As polysulfide is the main intermediate species, this mechanism is known as polysulfide pathway (Schippers and Sand 1999).In this case, not only iron- but also sulfur-oxidizing microorganisms can catalyze the dissolution of such sulfides while in the first case, only iron oxidizers are suitable.
