Description and Significance. Thiobacillus denitrificans is short rod-shaped (0.5×1.0-3.0 um), Gram-negative, obligately chemolithoautotrophic, and a member of the beta- subclass of the Proteobacteria.Different from many known chemolithotrophic sulfur-oxidizing bacteria (such as Acidithiobacillus ferrooxidans) which are strictly aerobic, T. denitrificans …
The most-studied leaching bacteria are from the genus Acidithiobacillus. Acidithiobacillus ferrooxidans and A. thiooxidans are acidophilic mesophiles and together with the moderate thermophile, A. caldus, they belong to the Gram-negative γ-proteobacteria [25].
A. ferrooxidans is a Gram negative rod shaped bacterium that is commonly found in deep caves or acid mine drainage, such as coal waste (10, 11, 12). These acidophilic bacteria thrive in optimal pH level of 1.5 – 2.5 where they convert insoluble metals to their soluble state. Even low concentrations (ppm) of these metallic ions would be ...

Thiobacillus ferrooxidans. [ ‚thī·ō·bə‚sil·əs fə′räk·sə‚danz] (microbiology) An aerobic rod-shaped microorganism that derives its energy from the oxidation of various sulfide minerals and soluble ferrous ion (Fe2+ ); it thrives in acidic environments of pH 1-3, conditions that would be fatal to most other life-forms.
The broad-host-range IncP plasmids RP4, R68.45, RP1::Tn501, and pUB307 were transferred to acidophilic, obligately chemolithotrophic Thiobacillus ferrooxidans from Escherichia coli by conjugation. A genetic marker of kanamycin resistance was expressed in T. ferrooxidans. Plasmid RP4 was transferred back to E. coli from T. ferrooxidans.

Thiobacillus is a genus of Gram-negative Betaproteobacteria. Thiobacillus thioparus is the type species of the genus, and the type strain thereof is the Starkey T strain, isolated by Robert Starkey in the 1930s from a field at Rutgers University in the United States of America.While over 30 "species" have been named in this genus since it was defined by Martinus Beijerinck in …
Acidithiobacillus ferrooxidans is a Gram-negative, γ-proteobacterium that thrives optimally at 30°C and pH 2, but can grow at pH 1 or lower [].It is abundant in natural environments associated with pyritic ore bodies, coal deposits, and their acidified drainages [2, 3].It is an important member of microbial consortia used to recover copper via a process …
