No other life form on the planet is not infiltrated our environment as successful as tiny single-celled bacteria. Among millions of roles that different species have on Earth, it appears that some microbes are experts in clearing precious metals .
An international team of researchers has found how a bacterium metaloyadna, Cupriavidus metallidurans, able to accept toxic metal compounds and not just to thrive, but also took some goldbits as a side effect of the toxic breakfast. Like many other elements, gold can pass through etc. biogeochemical cycle, during which it dissolves, carries around and finally concentrate again in sedimentary rocks on Earth. Microbes are involved in each step of the process that has led scientists to check whether they are poisoned by highly toxic compounds that gold ions normally form in the soil. Well, not Cupriavidus metallidurans - she managed somehow to "bold" gold-toxic compounds and convert them into metal form of the element, apparently without any threat to the life of the organism.
