Use of magnetic nanoparticles to enhance biodesulfurization [PDF]
, 2008 Biodesulfurization (BDS) is an alternative to hydrodesulfurization (HDS) as a method to remove sulfur from crude oil. Dibenzothiophene (DBT) was chosen as a model compound for the forms of thiophenic sulfur found in fossil fuels; up to 70% of the sulfur ...

The Alternating Growth of Bacteria within a Consortium During Desulfurization of Coal
Environment and Natural Resources Journal, 2022 Efforts to reduce organic sulfur in coal are taken through biodesulfurization by using desulfurization bacteria to release covalently-bound sulfur from the coal matrix. Coal is a complex hydrocarbon material that requires collaboration from more than one

Environmental Microbiology, Volume 24, Issue 4, Page 1946-1963, April 2022., 2022 Summary A new operon for biodesulfurization (BDS) of dibenzothiophene and derivatives has been isolated from a metagenomic library made from oil‐contaminated soil, by selecting growth of E. coli on DBT as the sulfur source. This operon is similar to a dszEABC operon also isolated by metagenomic functional screening but exhibited substantial differences:
