Metabolism[edit]
Sulfolobus solfataricus is known to grow chemoorganotrophically, in presence of oxygen, on a variety of organic componds such as sugars, alcohols, amino acids and aromatic compounds like phenol[1].
It uses a modified Entner-Doudroff pathway for glucose oxidation and the resulting pyruvate molecules can be totally mineralized in TCA cycle.[1]
Molecular oxygen is the only known electron acceptor at the end of the electron tranport chain[2].
Other than organic molecules, this Archea species can also utilize hydrogen sulfide [3] and elementar sulfur as electron donors and fix CO2 , possibly by means of HP/HB cycle[1], making it also capable of living chemoautotrophycally.
Recent studies have found also the capability of growing, albeit slowly, oxidizing molecular hydrogen[4].
