Summary The precipitation of gold(I) cyanide by removal of one cyanide group from dicyanoaurate by Acinetobacter RFB1 is reported. In the absence of essential salts but in the presence of ferrous ions, precipitation of gold(I) cyanide could be achieved without growth of the microorganism. Maximal precipitation was also dependent on the level of dissolved oxygen in the reaction media. Silver cyanide and other metal cyanide salts could not be precipitated as effectively as gold(I) cyanide. This system may find application in the separation of gold from other metal cyanide complexes in mining eluants.
