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 ...

Insights on the structure and stability of Licanantase: a trimeric acid-stable coiled-coil lipoprotein from Acidithiobacillus thiooxidans. [PDF]

PeerJ, 2014
Licanantase (Lic) is the major component of the secretome of Acidithiobacillus thiooxidans when grown in elemental sulphur. When used as an additive, Lic improves copper recovery from bioleaching processes. However, this recovery enhancement is not fully

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

Single and cooperative bioleaching of sphalerite by two kinds of bacteria—Acidithiobacillus ferriooxidans and Acidithiobacillus thiooxidans

Transactions of Nonferrous Metals Society of China, 2008
Abstract A cooperative bioleaching ( Acidithiobacillus ferriooxidans and Acidithiobacillus thiooxidans ) and single bioleaching ( Acidithiobacillus ferriooxidans or Acidithiobacillus thiooxidans ) of sphalerite were investigated by X-ray diffractometry, energy dispersive spectrography and scanning electron microscopy.
