生物浸出过程中微生物协同作用机制的研究进展

摘要

在生物浸出过程中，不同类型的浸矿微生物相互影响、相互促进，提高各自的代谢活动，从而提高金属浸出率。综述浸矿微生物协同作用的类型铁氧化菌与硫氧化菌、自养菌与异养菌、吸附菌与游离菌以及常温菌与高温菌的协同作用以及它们之间的作用机制，并分析协同作用的研究思路及生物浸出过程中矿物的溶解途径，重点介绍协同作用的研究方法和关键代谢产物及其作用。%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.
