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 ...

Bioleaching Coal Gangue with a Mixed Culture of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans [PDF]

Minerals, 2021
A mixed culture of A. ferrooxidans and A. thiooxidans isolated from a coal gangue dump was used to bioleach coal gangue in a column reactor to investigate the leaching of elements. The changes of metal ions (Fe, Mn and Cr) and sulfate in the leaching solution, elemental composition, mineral components and sulfur speciation of the coal gangue before and

Construction of recombinant mercury resistant Acidithiobacillus caldus [PDF]

Microbiological Research, 2011
A mercury-resistant plasmid of pTMJ212 which was able to shuttle between Acidithiobacillus caldus and Escherichia coli was constructed by inserting the mercury resistant determinants, the mer operon of Acidithiobacillus ferrooxidans, into the IncQ plasmid of pJRD215.

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

Metabolomics, 2012
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 ...

Pyrite oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide [PDF]

, 2012
Hydrogen peroxide (H2O2) at a micromolar level played a role in the microbial surface oxidation of pyrite crystals under initially neutral pH. When the mineral-bacteria system was cyclically exposed to 50 μM H2O2, the colonization of Acidithiobacillus ...

Microbial leaching of marmatite by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans

Transactions of Nonferrous Metals Society of China, 2006
The bioleaching of marmatite in shaken flasks was studied. After leaching for 29 days, the leaching ratio of zinc was 91%. Three kinds of bacteria, mixture-based bacteria, 9K-based bacteria and sulfur-based bacteria were used in marmatite leaching, of which the mixture-based bacteria have the best leaching result while the sulfur-based bacteria have ...

Phylogenetic heterogeneity of the species Acidithiobacillus ferrooxidans [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2003
Polyphasic genotypic analysis of 25 Acidithiobacillus ferrooxidans strains isolated from ores and ore concentrates collected in different regions of the world showed considerable strain heterogeneity. Restriction patterns of the chromosomal DNA of these strains obtained by PFGE were specific for each strain.
