冶金微生物的铁硫代谢多样性及其与矿物的相互作用

Diversity of iron and sulfur metabolism in bioleaching microorganisms and their interaction with minerals

生物冶金是利用微生物铁硫元素代谢活性加速硫化矿物氧化溶解,并对其中有价金属加以提取回收的技术。冶金系统中微生物的代谢多样性及其耦合功能网络,尤其是以铁硫代谢途径为主的功能网络,在硫化矿物加速氧化溶解过程中承担了重要作用,是生物冶金技术理论研究的核心领域。本文归纳了冶金系统中多样化的微生物物种及其铁硫代谢途径,并从微生物代谢耦合角度探讨了微生物代谢多样性与矿物的相互作用。

Bioleaching is to extract valuable metals from their ores by mlcroolal metaooHc aCLIWLy L, ^--~＇~ iron/sulfur. Microbial metabolic diversity and coupling function networks in metallurgical systems, especially functional networks dominated by iron and sulfur metabolism, play a major role in driving and accelerating the dissolution process of sulfide ore. Therefore, it is the core research area on bio-metallurgy technology. We summarize here the microbial diversity and iron/sulfur metabolism pathways in the metallurgical system, as well as the interactions between microbial metabolism diversity and minerals from the perspectives of metabolic coupling functional network.
