Abstract: | Summary Three species of Sulfate-Reducing Bacteria (SRB) were able to grow using dibenzothiophene (DBT) as their sole source of sulfur and sole electron acceptor. Desulfotomaculum orientis and Desulfovibrio desulfuricans were grown at 30°C while Thermodesulfobacterium commune was grown at 60°C, in media containing lactate and citrate. Hydrogen sulfide was the product of dissimilatory sulfur reduction.Research supported by the Office of Oil and Gas Processing of Fossil Energy, U.S. Department of Energy under contract DE-AC05-84OR21400 with Martin Marietta Energy Systems Inc. |
