Abstract
The genetic diversity of microbial communities that developed naturally within the system of ore heap–solution of heap leaching process has been studied. The difference in the microbial community structure is identified. It is found that phylotypes Serratia and Achromobacter dominated within the ore heap and Hydrogenophaga and Acinetobacter dominated in the solution. Phylogenetic analyses revealed that there are microorganisms among the closest homologues that are able to destruct toxic compounds and/or exhibit their enzyme activity at low temperature. It is shown that aerobic organoheterotrophs are the most promising for the isolation from autochthonous microbial communities of technogenic complexes in East Siberia, as well for studying their destructive potential and use in bioremediation.
