Sulfolobus solfataricus is a thermoacidophile, and was first characterized in sulfur-rich volcanic springs in Yellowstone National Park. Strains of S. solfataricus have also been found in hot mud pools in the Solfatara crater north of Naples, Italy. It has also been discovered in El Salvador and the Dominica. While the optimum temperature for growth is ≈75oC, S. solfataricus can live in a range of 55-90oC. It can live in a pH range of 0.9-5.8, with its optimum being 2-3. However, S. solfataricus maintains its cytoplasmic pH at 6.5. It has also been shown that S. solfataricus requires an aerobic environment, in which it is a free-living sulfur chemolithotroph. | |||
