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.
