Who discovered Thiobacillus ferrooxidans?

Acidithiobacillus ferrooxidans has emerged as an economically significant bacterium in the field of biohydrometallurgy, in the leaching of sulfide ores since its discovery in 1950 by Colmer, Temple and Hinkle.

What is acidithiobacillus Ferrooxidans used for?

Acidithiobacillus ferrooxidans is a major participant in consortia of microorganisms used for the industrial recovery of copper (bioleaching or biomining). It is a chemolithoautrophic, γ-proteobacterium using energy from the oxidation of iron- and sulfur-containing minerals for growth.

What is Thiobacillus Novellus?

Thiobacillus novellus is a facultatively chemolithoautotrophic and methylotrophic, Gram-negative, rod-shaped sulfur bacterium, shown by 16S rRNA gene sequence analysis to be a member of the alpha-2 subclass of the Proteobacteria.

Is Thiobacillus an Acidophile?

Acidithiobacillus thiooxidans, formerly known as Thiobacillus thiooxidans, is an acidophilic bacterium that oxidizes S0 and thiosulfate, but not iron.

Where is Thiobacillus found?

This species is widely found in soil, mud, freshwater- and marine sediments, sewage and industrial waste-treatment ponds and digestion tanks which are under anoxic conditions. T. denitrificans can remediate natural groundwater and engineered water treatment systems by removing excess nitrate.

Which process is performed by Thiobacillus Thiooxidans?

Which of the following processes is performed by Thiobacillus thiooxidans? Explanation: Thiobacillus thiooxidans, an autotroph, is capable of oxidizing elemental sulphur to sulphates. a) Desulfotomaculum sp. Explanation: Sulphates are reduced to hydrogen sulphide by soil microorganisms like Desulfotomaculum species.

What is the role of Thiobacillus ferrooxidans in AMD formation?

ferrooxidans grows under anaerobic conditions, it accelerates the dissolution of the ferric iron oxy-hydroxide by oxidation of elemental sulfur, which is a common reduction of iron. This is a key reaction in the “Ferredoks” process for extracting nickel from ore laterite.

What is meant by Thiobacillus?

Medical Definition of thiobacillus 1 capitalized : a genus of small rod-shaped bacteria (family Thiobacteriaceae) that live in water, sewage, and soils, derive energy from oxidation of sulfides, thiosulfates, or elemental sulfur, and obtain carbon from carbon dioxide, bicarbonates, or carbonates in solution.

Is Thiobacillus a denitrifying bacteria?

Summary. Thiobacillus denitrificans is a chemoautotrophic microorganism which is able to denitrify utilizing sulphides as electron donors. Its presence resulted in a high denitrification rate, oxidizing sulphide to sulphate, and reducing nitrate to nitrogen gas.

Is Thiobacillus a photosynthetic bacteria?

Phylogenetic analyses based on 16S rDNA sequences and genomic DNA-DNA relatedness showed that the sulphur-oxidizing facultative chemolithotroph Thiobacillus acidophilus was closely related to members of the genus Acidiphilium, which is a group of strictly aerobic, heterotrophic acidophiles now categorized into aerobic …

Is Thiobacillus a Sulphur bacteria?

The most common microorganisms associated with sulfide oxidation are Thiobacillus spp. These non-spore-forming bacteria belong to the colorless sulfur bacteria.

What is the use of Thiobacillus?

Thiobacillus, widespread in marine and terrestrial habitats, oxidizes sulfur, producing sulfates useful to plants; in deep ground deposits it generates sulfuric acid, which dissolves metals in mines but also corrodes concrete and steel.

Where do Acidithiobacillus ferrooxidans get their energy from?

Acidithiobacillus ferrooxidans (basonym Thiobacillus ferrooxidans) can be isolated from iron-sulfur minerals such as pyrite deposits, oxidising iron and sulfur as energy sources to support autotrophic growth and producing ferric iron and sulfuric acid.

Where can Thiobacillus denitrificans be found in the world?

This species is widely found in soil, mud, freshwater- and marine sediments, sewage and industrial waste-treatment ponds and digestion tanks which are under anoxic conditions. T. denitrificans can remediate natural groundwater and engineered water treatment systems by removing excess nitrate.

Why are Acidithiobacillus ferrooxidans unfavorable on acidic iron agar?

Cultivation of A. ferrooxidans is unfavorable on acidic ferrous iron agar because growth becomes inhibited by agar hydrolyzed products like: pyruvic acid, citric acid, oxaloacetic acid and glucose (18). Members of the genus Acidiphilium are oligotrophs, preferring low concentrations of organic compounds in growth media.

How big is the genome of ferrooxidans Acidithiobacillus?

Genome Structure. Two strains of Acidthiobacillus ferrooxidans have been successfully and completely sequenced. The strains sequenced are ATCC 53993 and ATCC 23270 which consists of genomic sizes of 2.88kb and 2.98kb respectively. Acidithiobacillus ferrooxidans contains a single circular chromosome consisting of around 3,000 genes.
