Sulfolobus is one of the best-studied members of Crenarchaeota. Sulfolobus members are spherical, aerobic, and irregularly lobed. They can thrive in a temperature optimum of about 80 ̊ C and the pH optimum of 2-3. Thus, they are referred to as thermoacidophiles. Under oxic conditions, Sulfolobus species able to grow chemoorganotrophically and also grow chemolithoautotrophically, consuming H 2 S, H 2 , and FeS 2 as electron donors and consuming oxygen as the terminal electron acceptor (though the use of ferric iron has been reported). Sulfolobus species use HP/HB cycle when growing chemolithoautotrophically and when growing chemoorganotrophically, they use the Entner-Doudoroff pathway (nonphosphorylative version), and tricarboxylic acid cycle (TCA).
