Description
Acidithiobacillus ferrooxidans is a Gram-negative extremophile acidophile belonging to the phylum Pseudomonadota. It is a chemolithoautotrophic microorganism capable of oxidizing ferrous iron (Fe²⁺) to ferric iron (Fe³⁺) and reducing sulfur compounds to sulfuric acid, thereby obtaining energy. Therefore, Acidithiobacillus ferrooxidans can be used as a biofertilizer to dissolve iron in the soil and enhance nutrient availability, which is crucial for plants in iron-deficient soils. In addition, it has shown potential in environmental remediation and wastewater treatment.
