This article offers a general overview of the microbiology of Spainís Rio Tinto. It introduces the history of the Rio Tinto, briefly describes some of the organisms that live there, and examines a few implications of the biological diversity for evolutionary studies. The article also explains that the acidic condition of the water may not be entirely due to mining activities, rather to the presence of specialized bacteria. It includes images of the Rio Tinto and diatoms.
