Biodegradation of dibenzothiophene by a nodulating isolate of Rhizobium meliloti

open access: yes, 1998
Rhizobium meliloti Orange 1 was isolated from aerobic sediments of a drainage ditch receiving oil refinery leakage. This bacterium has been shown to be capable of growing on dibenzothiophene as the sole carbon and energy source.

Oxidation of Dibenzothiophene to Dibenzothiophene Sulfone Using Tungsten (VI) Oxide [PDF]

open access: yes, 2013
The oxidation of dibenzothiophene (DBT) to dibenzothiophene-sulfone has been considered as an alternate method to remove sulfur from crude oil. This study demonstrates that the oxidative desulfurization (ODS) of DBT to DBT-sulfone occurs using WO3 as a ...
