Biomining and bacteria. BACTERIA are a mixed blessing. On the one hand, they plague us with diseases such as tuberculosis and leprosy and on the other, they provide us with such delights as curd and wine. Now, we have bacteria that are miners. In the past few years, these diminutive diggers have become the darling of the mining industry.

Genetically modified organisms (GMOs) are organisms which have had their genetic codes altered through direct manipulation of the deoxyribonucleic acid (DNA). This is present in all cells and is the means whereby characteristics are passed down from one generation to another.

Biomining with acidophilic microorganisms has been used at commercial scale for the extraction of metals from various sulfide ores. With metal demand and energy prices on the rise and the concurrent decline in quality and availability of mineral resources, there is an increasing interest in applying biomining technology, in particular for leaching metals from low grade minerals and wastes.

Biomining is becoming popular because it is cheap, reliable, efficient, safe, and environmentally friendly, unlike traditional mining methods. The efficiency of biomining can be increased either by finding suitable strains of microorganisms or by genetically modifying existing microorganisms, made possible due to rapid advances in the field of ...
Genetically modified organisms Main article: Genetically modified organism Plants, animals or micro organisms that have changed through genetic engineering are termed genetically modified organisms or GMOs. Bacteria were the first organisms to be genetically modified. Plasmid DNA containing new genes can be inserted into the bacterial cell and the bacteria will then express those genes.

Certain genetically modified microbes can also be used in biomining and bioremediation, due to their ability to extract heavy metals from their environment and incorporate them into compounds that are more easily recoverable.
Although some procedures to genetically modify a few of the biomining microorganisms are available, greater advances are required in this area (Jerez, 2017). This in turn would allow to genetically modify the entire extremophilic microbiome to obtain much more efficient and controlled metal concentration processes, redefining the current metal ...
