The Midas Bug -- the bacterial alchemy of gold

ecipitation.

"A unique attribute of R. metallidurans is that it is able to survive in concentrations of gold that would kill most other micro-organisms."

This research has significance for the mineral exploration industry as current models of gold formation do not include a biological mechanism.

"There may be new opportunities for the bio-processing of gold ores now that we have discovered bacteria that precipitants gold out of solution," Dr Reith said.
