The experiments on the enrichrnent of gold by bacteria indicate that bacteria have a very intense capacity of enriching gold and act as an arrester of trace gold in sea water. Bacteria enrich gold in two forms: absorption and adsorption. Absorption means that gold finds its way into organisms and it is combined with the mercapto group of protein, whereas adsorption means that gold is adsorbed on organisms by amino acid secreted by cell walls. Bacteria are organisms with very high vitality and reproductive capacity and huge productivity in nature. Bacteria, which are important geological agents for gold enrichment and can exert effects on geological environments by their metabolism, are of important geochemical significance fOr the formation of gold-bearing black rock series.
