Abstract:

 

The ability of the hyperthermophilic archaeon Sulfolobus solfataricus P2 to grow on organic and  inorganic sulfur sources was investigated. A sulfur-free mineral medium was  employed with different sources of carbon. The results showed that inorganic  sulfur sources display growth curve patterns significantly different from  the curves obtained with organic sulfur sources. Solfataricus has the ability to utilize  DBT and its derivatives, but it lacks BT utilization.  Solfataricus} utilizes DBT at a  rate of 1.23 \mu mol 2-HBP h^{-1} g DCW^{-1} even at 78 °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 \mu M DBT g DCW^{-1} h^{-1}.  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.
