Bioleaching Microbial Community Metabolism and Composition Driven by Copper Sulphide Mineral Type. [PDF]

Environ Microbiol Rep
Bioleaching is a microbially mediated green technology for the recovery of metals from ore. Here, microbial consortia from a copper bioleaching column in Cyprus were cultivated on chalcopyrite (CuFeS2) and then sub‐cultured on chalcocite (Cu2S) and chalcopyrite to investigate how mineral type and surface chemistry influence microbial community ...

Understanding a Core Pilin of the Type IVa Pili of Acidithiobacillus thiooxidans, PilV. [PDF]

J Microbiol Biotechnol
Pilins are protein subunits of pili. The pilins of type IV pili (T4P) in pathogenic bacteria are well characterized, but anything is known about the T4P proteins in acidophilic chemolithoautotrophic microorganisms such as the genus Acidithiobacillus. The interest in T4P of A.

Optimization of biological sulfuric acid generation by Acidithiobacillus thiooxidans in a stirred-tank reactor system [PDF]

Applied Microbiology and Biotechnology
Conventional sulfuric acid production is tied heavily to the fossil fuel industry, where it is typically obtained from the desulfurization of fuels. Here, the biological production of sulfuric acid by Acidithiobacillus thiooxidans in a reactor setup was ...

Metabolomic study of Chilean biomining bacteria Acidithiobacillus ferrooxidans strain Wenelen and Acidithiobacillus thiooxidans strain Licanantay. [PDF]

Metabolomics, 2013
In this study, we present the first metabolic profiles for two bioleaching bacteria using capillary electrophoresis coupled with mass spectrometry. The bacteria, Acidithiobacillus ferrooxidans strain Wenelen (DSM 16786) and Acidithiobacillus thiooxidans strain Licanantay (DSM 17318), were sampled at different growth phases and on different substrates ...

Synergistic recovery of Pr, Eu, and Ce from gold mine tailings using bioleaching and oxalic acid pretreatment [PDF]

Scientific Reports
Mining activities produce a significant amount of gold mine tailings (GMT) rich in rare earth elements. Despite this, little information is available regarding the effective extraction of these precious elements from GMT. We describe a novel strategy for
