solfataricus has been found in different areas including Yellowstone National Park, Mount St. Helens, Iceland, Italy, and Russia to name a few. Sulfolobus is located almost wherever there is volcanic activity. They thrive in environments where the temperature is about 80 °C with a pH at about 3 and sulfur present.

Where is Thermoproteus found?

Members of Thermoproteus are found in acidic hot springs and water holes; they have been isolated in these habitats in Iceland, Italy, North America, New Zealand, the Azores, and Indonesia. Their optimal growth temperature is 85 °C.

What does Sulfolobus produce?

Sulfolobus spp. produce an interesting class of antibiotic proteins and peptides which are known under the term archaeocins, or more specifically sulfolobicins (Prangishvili et al., 2000; O'Connor and Shand, 2002; Besse et al., 2015).
