Effect of Acidithiobacillus ferrooxidans on pyrolusite bioleaching

工程科学学报, 2019
Biohydrometallurgy is an increasingly popular ore extraction technology and is especially applicable for low-grade ores. In particular, Acidithiobacillus ferrooxidans (A. ferrooxidans) is by far the most widely used bioleaching microorganism for leaching

Unveiling the Bioleaching Versatility of Acidithiobacillus ferrooxidans. [PDF]

Microorganisms
Acidithiobacillus ferrooxidans is a Gram-negative bacterium that thrives in extreme acidic conditions. It has emerged as a key player in biomining and bioleaching technologies thanks to its unique ability to mobilize a wide spectrum of elements, such as Li, P, V, Cr, Fe, Ni, Cu, Zn, Ga, As, Mo, W, Pb, U, and its role in ferrous iron oxidation and ...

Lipopolysaccharides of iron-oxidizing Leptospirillum ferrooxidans and Thiobacillus ferrooxidans.

The Journal of General and Applied Microbiology, 1988
Lipopolysaccharides were isolated from one strain of Leptospirillum ferrooxidans and three strains of Thiobacillus ferrooxidans. All strains contained 2-keto-3-deoxyoctonate (KDO), heptose(s) and glucosamine besides neutral sugars, but were devoid of phosphorus.

Growth of Thiobacillus ferrooxidans on Formic Acid [PDF]

Applied and Environmental Microbiology, 1991
A variety of acidophilic microorganisms were shown to be capable of oxidizing formate. These included Thiobacillus ferrooxidans ATCC 21834, which, however, could not grow on formate in normal batch cultures. However, the organism could be grown on formate when the substrate supply was growth limiting, e.g., in ...

U mobilization and associated U isotope fractionation by sulfur-oxidizing bacteria

Frontiers in Microbiology, 2023
Uranium (U) contamination of the environment causes high risk to health, demanding for effective and sustainable remediation. Bioremediation via microbial reduction of soluble U(VI) is generating high fractions (>50%) of insoluble non-crystalline U(IV)

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.

Estudo da dissolução oxidativa microbiológica de uma complexa amostra mineral contendo pirita (FeS2), Pirrotita (Fe1-xS) e Molibdenita (MoS2) Microbiological oxidative dissolution of a complex mineral sample containing pyrite (FeS2), pyrrotite (Fe1-xS) and molybdenite (MoS2)

Química Nova, 2007
This work aims to study the oxidation of a complex molybdenite mineral which contains pyrite and pyrrotite, by Acidithiobacillus ferrooxidans. This study was performed by respirometric essays and bioleaching in shake flasks.
