Researchers Find Bacterium with Potential to Make Microscopic Gold Nuggets

GoldPublished in the journal Nature Chemical Biology this Monday, a study has discovered that toxic water-soluble gold can be converted into the metal's microscopic nuggets. The amazing part is that it is a bacterium that has the potential to do the same.

As per the findings, biochemists have been intrigued by a mystery for many decades and the study conducted lately has solved the same. They were investigating into the reason for the frequent presence of the Delftia acidovorans germ on the tiny gold nuggets' surface.

A colony of the microorganism was formed by Nathan Magarvey and colleagues so they could know how the molecular-sized gold nuggets are produced by it outside its cell wall.

The University of Adelaide's microbiologist Frank Reith from Australia is of the opinion that the findings probably open a way to use a bacterium or metabolite when waste-drop piles need to be sowed. He had worked on gold-processing bacteria, which had proved to be a benchmark for Magarvey's team.

He added that the way of leaving waste-drop piles standing for years is also opened with the study. "This finding is the first demonstration that a secreted metabolite can protect against toxic gold and cause gold biomineralisation", affirmed the researchers.
