Abstract:During bioleaching, different types of mixed bacteria interact and cooperate with each other to improve their metabolic activities and increase the metal extracting rate. The synergy types of microorganisms, such as the synergy of iron-oxidizing bacteria and sulfur-oxidizing bacteria, the synergy of autotrophic bacteria and heterotrophic bacteria, the synergy of adsorbed bacteria and free bacteria and the synergy of mesophilic bacteria and thermophilic bacteria and the mechanism of their interactions were reviewed. And the synergy and mineral dissolution ways during bioleaching were discussed, the research methods of the synergy and the roles of important metabolites were discussed.
Key words: leaching microbes; synergy mechanism; ecological methods; functional genes; mineral dissolution
