A Biotechnological Strategy for Molybdenum Extraction Using Acidithiobacillus ferrooxidans

Applied Biochemistry and Biotechnology, 2020
Biosorption is a potential tool for the extraction of metals from contaminated water and recovery of precious metals, which is a convenient alternative to conventional processes. In the present study, molybdenum recovery by Acidithiobacillus ferrooxidans strain ZT-94 was evaluated.

Ferrous sulphate oxidation using thiobacillus ferrooxidans: a review

Process Biochemistry, 1995
The ability of the chemolithotrophic bacterium Thiobacillus ferrooxidans to oxidise ferrous sulphate has been exploited in the process of bioleaching, treatment of acidic mine drainage and removal of H2S from sour gases. Over the years, much attention has been paid to this organism and the process it catalyses. Unfortunately, inconsistent and ambiguous

A Novel Mineral Flotation Process Using Thiobacillus ferrooxidans

Applied and Environmental Microbiology, 1999
ABSTRACT Oxidative leaching of metals by Thiobacillus ferrooxidans has proven useful in mineral processing. Here, we report on a new use for T. ferrooxidans , in which bacterial adhesion is used to remove pyrite from mixtures of sulfide minerals during flotation.

Comparative genomic analysis ofAcidithiobacillus ferrooxidansstrains using theA. ferrooxidansATCC 23270 whole-genome oligonucleotide microarray

Canadian Journal of Microbiology, 2009
Acidithiobacillus ferrooxidans is an important microorganism used in biomining operations for metal recovery. Whole-genomic diversity analysis based on the oligonucleotide microarray was used to analyze the gene content of 12 strains of A. ferrooxidans purified from various mining areas in China. Among the 3100 open reading frames (ORFs) on the slides,

Identification of a gene encoding a tetrathionate hydrolase in Acidithiobacillus ferrooxidans

Journal of Biotechnology, 2007
Tetrathionate is one of the most important intermediates in dissimilatory sulfur oxidation and can itself be utilized as a sole energy source by some sulfur-oxidizing microorganisms. Tetrathionate hydrolase (4THase) plays a significant role in tetrathionate oxidation and should catalyze the initial step in the oxidative dissimilation when sulfur ...
