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

Abstract:

Bioleaching is to extract valuable metals from their ores by microbial metabolic activity to take 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.
