Biodesulfurization and the upgrading of petroleum distillates
Current Opinion in Biotechnology, 2000Biotechnology offers an alternative way to process fossil fuels. There have been several important advances in the elucidation of the mechanisms of biodesulfurization and the development of a biocatalytic desulfurization process. These include a detailed analysis of the rate and extent of desulfurization of real target molecules in a diesel matrix, the

Thermophilic biodesulfurization and its application in oil desulfurization
Applied Microbiology and Biotechnology, 2018To reduce the harm caused to the environment by fuel combustion and meet the increasingly stringent emission standards, the sulfur content of fuels should be reduced. Dibenzothiophene, benzothiophene, and their derivatives are sulfur-containing components of fuels that are difficult to desulfurize and can therefore cause great environmental damage ...

Biodesulfurization of fossil fuels
Current Opinion in Microbiology, 2003Biotechnological techniques enabling the specific removal of sulfur from fossil fuels have been developed. In the past three years there have been important advances in the elucidation of the mechanisms of biodesulfurization; some of the most significant relate to the role of a flavin reductase, DszD, in the enzymology of desulfurization, and to the ...

Anaerobic biodesulfurization in different inoculums
Global NEST International Conference on Environmental Science & Technology, 2022Sulfur compounds in liquid fuel are undesirable and the level of these compounds in diesel fuel is strictly regulated in the last 15 years by the European Union. These stringent regulations are imposing an urgent requirement for fuel terminals to produce fuels having ultra-low sulfur content.

Enhanced dibenzothiophene biodesulfurization in a microchannel reactor
Biotechnology Letters, 2007A microchannel reactor system was used in a biodesulfurization process in which the rate of biodesulfurization in the oil/water phase of the microchannel reaction was more than nine-fold that in a batch (control) reaction. In addition, the microchannel reaction system using a bacterial cell suspension degraded alkylated dibenzothiophene that was not ...

Oil biodesulfurization: A review of applied analytical techniques
Journal of Chromatography B, 2021The wide use of fossil fuels and their associated environmental concerns, highlighted the importance of affordable and clean energy (goal 7), as adopted by the Sustainable Development Goals of the United Nations for 2030. For years now, the detection of sulfur components in liquid fuels is performed mainly for environmental and health purposes in ...

Biodesulfurization of organic-sulfur compounds
Current Microbiology, 1993A screening assay in which dibenzothiophene (DBT) or DBT-sulfone served as the only bioavailable source of sulfur was used to obtain two new bacterial isolates, strains UM9 and UM3, that desulfurized either substrate. Strain UM9 produced the desulfurized product, 2-hydroxybiphenyl (HBP); no other identifiable desulfurized products or released sulfate ...

Enhancement of bunker oil biodesulfurization by adding surfactant
World Journal of Microbiology and Biotechnology, 2012Biodesulfurization (BDS) is a promising method to remove sulfur compounds from diesel and gasoline. However, the information on BDS of heavy oil is scanty, which might be due to their "undesirable" physical properties and more complicated sulfur diversities. In this study, the BDS of one kind of heavy oil, bunker oil MFO380 was investigated.

Recent Developments in Biodesulfurization of Fossil Fuels
2009The emission of sulfur oxides can have adverse effects on the environment. Biodesulfurization of fossil fuels is attracting more and more attention because such a bioprocess is environmentally friendly. Some techniques of desulfurization have been used or studied to meet the stricter limitation on sulfur content in China.
