Abstract

The ability of hyperthermophilic archaeon, Sulfolobus solfataricus P2, to grow on organic and inorganic sulfur sources was investigated. A sulfur free mineral medium has been employed with different sources of carbon. Results showed that inorganic sulfur sources display growth curve patterns significantly different from the curves obtained with organic sulfur sources. Solfataricus has an ability to utilize DBT and its derivatives, but it lacks BT utilization. Solfataricus utilizes DBT at a rate of 1.23 μmol 2-HBP h-1 g DCW-1 even at 78 o40 C, at which DBT is known to be unstable. After enabling DBT stabilization using a two-phase culture system, stable microbial growth was achieved showing a desulfurization rate of 0.34 μM DBT g DCW-1 h-143 . Solfataricus offers beneficial properties compared to the other desulfurizing mesophilic/moderate thermophilic bacteria due to its capacity to utilize DBT and its derivatives under hyperthermophilic conditions.
