Biomining is a technique used to recover the various types of minerals from ore using microorganism. It method is cheap, reliable, efficient and also environmentally friendly method of mineral recovery. Using biotechnology efficiency of biomining can be increased by using genetically modified microorganisms.
By employing genome mining followed by an one strain many compounds (OSMAC)based approach, we have identified the previously unreported capability of a marine spongederived isolate, namely Streptomyces sp. SM17, to produce surugamide A. Phylogenomics analyses provided novel insights on the distribution and conservation of the surugamides ...

Scientists discover bacteria that can make gold out of mine waste ... Finance Corp. will invest in countries disregarded by other companies as part of a plan to double its exposure to the mining ...
Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the waterinsoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of ores because as they oxidize the ore, they open up ...

8 hours ago· While the engagement of Chinese migrants in smallscale mining in Ghana has gained traction in scholarship, the extant literature pays little attention to how the relationship between the socalled formal institutions (, the Minerals Commission and Ministry of Land and Natural Resources) and informal institutions (, the chieftaincy and customary land institutions) enables illegalities ...
That''s why researchers have become increasingly keen to get these microbes on the mining payroll. They''re looking for ways to use bacteria and archaea to extract metal from rock as well ...
characteristics, microorganisms can also be identified by their biochemical "signatures": • the nutrient requirements and metabolic "byproducts" of of a particular microorganism • different growth media can be used to test the physiological characteristics of a microorganism •, medium with .
for bioleaching capabilities of bacteria begins with isolation and identification of pure cultures. Literature abound with different types of bacteria isolated from various mining sites around the world, there is need therefore to study those from Agbaja. Due to the diversity of micro organisms found within mining sites as reported in different
Mining releases many pollutants while the only chemicals released from biomining is any metabolites or gasses that the bacteria secrete. The same concept can be used for bioremediation models. Bacteria can be inoculated into environments contaminated with metals, oils, or other toxic compounds.

14 hours ago· Abstract. Lodgepole pine (Pinus contorta var. latifolia) trees have been thriving on unreclaimed gravel mining sites in British Columbia, Canada with tissue nitrogencontent and growthrate unaffected by extremely low soil indicates that pine trees could be accessing a hidden nitrogen source to fulfill their nitrogen requirements—possibly via endophytic nitrogenfixation.
