SCIENTISTS DISCOVERED A BACTERIA WHICH CONVERTS TOXIC METALS INTO GOLD

cupriavidus metallidurans . an international team of researchers found out how a metal gobbling bacterium, manages to ingest toxic metallic compounds and still thrive , producing tiny gold nuggets as a side effect.
Just like many other elements, gold can move through what's known as a biogeochemical cycle - being dissolved, shifted around, and eventually re-concentrated in Earth's sediment.

Microbes are involved in every step of this process, which has led scientists to wonder how they don't get poisoned by the highly toxic compounds that gold ions usually form in the soil.
C. metallidurans thrives in soils which contain both hydrogen and a range of toxic heavy metals. This means the bacterium doesn't have much competition from other organisms that can be easily poisoned in such an environment.
