Acidithiobacillus ferrooxidans is a type of bacteria that thrives in acidic environments, often found in mining sites and mineral-rich soils. It plays a crucial role in the bioleaching process, where it helps extract metals like copper and gold from ores by oxidizing iron and sulfur compounds. This bacterium is known for its ability to oxidize ferrous iron to ferric iron, which can then dissolve metal sulfides. Its unique metabolic processes make it important in bioremediation and environmental management, as it can help recover valuable metals while reducing the environmental impact of mining activities.
