adopt a bacterium: Cupriavidus metallidurans a bacteria of many "talents"

imagine manufacturing 24-karats of GOLD in the lab, thanks to Cupriavidus metallidus and Delftia acidovorans all that is possible now. Cupriavidus metallidus strain CH34 is a gram-negative, rod-shaped, non-spore forming bacteria, that works along side Delftia acidovorans to manufacture gold nuggets from toxic chemical solutions such as gold chloride. Cupriavidus metallidurans does not only convert toxic chemicals into gold but can also free water from heavy metal contaminants and can be used in biosensing

Cupriavidus metallidurans previously known as Ralstonia metallidurans, is a facultative anaerobe, gram negative bacterium that is rod-shaped. Cupriavidus metallidurans is famously known for its ability to withstand toxic environmental conditions, its gold nuggets production ability and resisting heavy toxic metals. Cupriavidus metallidurans is also used in biosensing and decontamination of heavy-metal consisting waste water since it can survive harsh conditions which other bacteria can not exist in.

Cupriavidus metallidurans: A Modern Alchemist

Recent discovery on the potential use of a bacterium has revealed that it can yield 24-carat gold in one week. Scientists from Michigan State University, USA, Kazem Kashefi, assistant professor of microbiology and Adam Brown, associate professor of electronic art and intermedia, found that a bacterium, Cupriavidus metallidurans (previously known as Ralstonia metallidurans) [1] that belongs to beta class of proteobacteria can grow on a substantial concentration of toxic gold chloride (also known as liquid gold). Further reports from Australia have confirmed this microbial process involved in cycling of gold, based on the 99 % similarity of 16S rDNA obtained from template (gold grains) to R. metallidurans [2]. The bacterium with such potential was first isolated in 1976 from the sludge of a metal processing factory located in Belgium [3]. Its ability to detoxify gold complexes by transforming them into metallic gold was discovered in 2009 [4]. When discovered, the bacterium was initially found to be resistant to cadmium but subsequent studies identified that this strain is multi-metal resistant and has two plasmids pMOL28 and pMOL30 which harbor multiple loci for metal resistance [5]. The plasmid pMOL28 contains genes involved in resistance to Co(II), Cr(VI), Hg(II) and Ni(II) which are present on a 34 Kb region, whereas a 132 Kb region on the plasmid pMOL30 contains the genes involved in resistance to the metals Ag(I), Cd(II), Co(II), Cu(II), Hg(II), Pb(II), and Zn(II) [5, 6]. The bacterium’s ability to thrive in toxic environments with a high number of heavy metal resistant genes makes it an excellent model organism to study the means by which microbes deal with heavy metal stress. Such unique ability of this extremophile to metabolize toxic substances might also provide an insight into understanding the origin of life.
