Biomineralization of Gold: Biofilms in Bacterioform Gold

Reith, Frank; Rogers, Steve L; McPhail, Derry; Webb, Daryl

Description

Bacterial biofilms are associated with secondary gold grains from two sites in Australia. 165 ribosomal DNA clones of the genus Ralstonia that bear 99% similarity to the bacterium Ralstonia metallidurans-shown to precipitate gold from aqueous gold(III) tetrachloride-were present on all DNA-positive gold grains but were not detected in the surrounding soils. These results provide evidence for the bacterial contribution to the authigenic formation of secondary bacterioform gold grains and nuggets.
