Metal Extraction and Bioleaching

The paper tests microbial biomining of asteroidal material in microgravity, finding that fungi enhance metal release but results vary, with space conditions affecting microbial metabolism.

This paper performs a trait-based meta-analysis of microbial guilds involved in iron redox cycling, identifying functional guilds and their ecological roles across diverse environments.

The paper profiles microbial communities in copper/nickel mine tailings using metagenomics and metaproteomics, revealing diverse metal resistance genes and novel taxa, along with challenges in low-biomass sequencing.

This paper identifies potential iron oxidation marker genes in Sideroxydans sp. CL21 by comparing gene expression under different growth conditions.

This paper compares the performance of three microbes in dissolving ultramafic rock dunite, finding that Gluconobacter oxydans outperforms the others in acid production and metal extraction.

The paper analyzes microbial communities in historic mine waste to assess their composition, activity, and geochemical associations, finding that they are dominated by inorganic nitrogen- and carbon-oxidizing taxa and contain rare iron and sulfur-cycling organisms.

This paper demonstrates that Gluconobacter oxydans produces biolixiviants that significantly accelerate the leaching of cations from ultramafic minerals compared to chemical alternatives.

This paper shows Sideroxydans lithotrophicus ES-1 uses magnetite as a solid electron donor for iron oxidation, with MtoA and cupredoxin proteins involved in this process.

The paper examines microbial communities in Cu/Ni mine tailings, finding high variability in diversity and composition linked to geochemical factors like pH and metal concentrations.

The paper identifies genetic factors in Gluconobacter oxydans that enhance rare earth element bioleaching, finding 304 genes affecting acid production and bioleaching efficiency.
