Let's learn about microbes
Let's learn about microbes. Scientists often grow bacteria in the lab on petri dishes. The dish is filled with food for the bacteria to eat. Any unicellular — one-celled — organism is a microbe. Microbes, short for microorganisms, are the largest group of living things on Earth. There may be a billion species of microbes, but only a small ...

Large-scale mining of mineral resources inevitably leads to serious heavy metal pollution. Heavy metal pollution has potential and is long-term, cumulative, and irreversible, posing a great threat to the environment and human health (Acosta et al. 2011).Soil microbes are more sensitive than animals and plants when subjected to heavy metal stress.

Arsenic-transforming microbes and their role in biomining
It is well known that microorganisms can dissolve different minerals and use them as sources of nutrients and energy. The majority of rock minerals are rich in vital elements (e.g., P, Fe, S, Mg and Mo), but some may also contain toxic metals or metalloids, like arsenic. The toxicity of arsenic is disclosed after the dissolution of the mineral, which …

Microbial Mining
Microbial Mining. This website is dedicated to the use of microbes in the mining of metals such as Iron, Copper and Uranium. In short, the main use of microbes in mining is in microbial leaching. This is the process whereby a microbe will reduce or oxidise an insoluble metal into a soluble form, which can then be extracted and used by us.
