Sulfur-binding protein of flagella of Thiobacillus ferrooxidans [PDF]
The sulfur-binding protein of Thiobacillus ferrooxidans ATCC 23270 was investigated. The protein composition of the bacterium's cell surface changed according to the culture substrate. Sulfur-grown cells showed greater adhesion to sulfur than iron-grown cells. The sulfur-grown cells synthesized a 40-kDa surface protein which was not synthesized by iron-

Nitrogen Fixation by Thiobacillus ferrooxidans [PDF]
Summary: Cultures of Thiobacillus ferrooxidans grown in the absence of a source of fixed nitrogen reduced acetylene to ethylene suggesting the presence of nitrogenase. This presumptive evidence has now been substantiated by the demonstration of the enrichment of 15N in the protein of the organism when grown under 15N2.

Sorption of Thiobacillus ferrooxidans to particulate material [PDF]
Iron-oxidizing thiobacilli oxidize many sulfide minerals. It has been suggested that one mechanism of the oxidation involves a mineral surface attack by the bacteria, thereby catalyzing chemical reactions that normally proceed at slow rates. Evidence for a direct surface attack by acidophilic thiobacilli has been obtained from scanning electron ...

Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Regeneration of leaching agent based on Fe2(SO4)3 with utilization of thionic bacteria [PDF]
The creation of bacterial film using Thiobacillus ferrooxidans and possibility of its utilization for regeneration of leaching agent based on Fe2(SO4)3 in the process of chalcopyrite leaching has been studied. Jarosites, the products of hydrolysis of Fe2(

Genome Analysis of the Biotechnologically Relevant Acidophilic Iron Oxidising Strain JA12 Indicates Phylogenetic and Metabolic Diversity within the Novel Genus "Ferrovum". [PDF]
BACKGROUND:Members of the genus "Ferrovum" are ubiquitously distributed in acid mine drainage (AMD) waters which are characterised by their high metal and sulfate loads.

Oxic microbial electrosynthesis (oMES) enables the conversion of renewable electricity and oxic industrial CO2‐streams into biomass by cultivating aerobic, autotrophic hydrogen‐oxidizing bacteria. This article presents the most promising candidates for oMES, discusses their biomass productivity and energy efficiency, and outlines research gaps to bring

Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the
