Biodesulfurization of fossil fuels is a promising method for treating the sour oil due to its environmental friendliness and ability to get rid of the recalcitrant organosulfur compounds. In this study, many types of microorganisms such as Ralstonia eutropha, Rhodococcus erythropolis, Acidithiobacillus ferrooxidans, and Acidithiobacillus thiooxidans applied on a sour heavy crude oil (sulfur content was 4.4%). Also, a colony isolated from the crude oil and oil concentrate was examined by supplying it with PTCC 106. The various official and famous mediums were significantly evaluated such as (PTCC 2, PTCC 105, PTCC 106 (9K), PTCC 116, PTCC 123, PTCC 132), sulfur-free MG-medium, basal salts medium, and mineral salts. It was found that Rhodococcus erythropolis and Acidithiobacillus ferrooxidans from microorganisms and SFM and the medium PTCC 105 were selected as the higher desulfurization efficiencies of crude oil equaling 47 and 19.74% respectively. The bioreactions depend on the treated fluid, targeting sulfur compounds as these represent the environmental status (amounts and types of nutrients), and the type of biotreaters whether microorganism are septic, semiseptic, or aseptic. The optimum operation conditions have been designed by using Definitive method such as mixing speed, temperature, surfactant dose, OWR, acidity. The optimum efficiencies obtained here are better than the previous efforts even though those gained by bioengineering. Biodesalination was a simultaneous process with the BDS.

“…BDS is considered environmentally friendly because it operates under mild conditions, at low pressure and temperature, and does not require the use of chemicals. 29 There are two main approaches to BDS: the oxidative C−C pathway (also known as Kodama's pathway) and the C−S cleavage pathway. 30 The C−S cleavage pathway is specific to sulfur and involves converting DBT into four intermediates: DBT sulfoxide, DBT sulfone, 2-hydroxybiphenyl-2-sulfinate (HPBS), and sulfite, which is referred to as the "4S" pathway.…”

Nowadays, the scientific community is actively researching the advancement of a sustainable effective desulfurization technique. The development of alternative or supplementary approaches to desulfurization has rapidly progressed in recent years. Among these approaches, the oxidative desulfurization (ODS) process stands out as a highly promising method. This can be attributed to its notable selectivity, cost-effectiveness, mild reaction conditions, and overall efficiency. It is essential to consider the role of oxidants, catalysts, and operating conditions in optimizing the ODS process. This review examines a comprehensive understanding of the ODS process and its potential applications in desulfurization. It highlights the importance of oxidants, extractant solvent, and other operating conditions in the ODS process and discusses the different groups of catalysts that can be used. In addition, the review examines five distinct groups of heterogeneous catalysts used in the ODS process: transition metal oxides stabilized, polyoxometalates, ionic liquids, carbon materials, and porous materials. The role of ionic liquids in catalytic and extractive oxidation is also explored. In recent years, alternative or supplementary desulfurization methods have been rapidly developed. The review discusses the advantages and disadvantages of each approach. It explores various techniques that can be employed to mitigate the drawbacks associated with each system.

“… Environment: The combustion of fossil fuels can result in the release of harmful components such as SO x , NO x , CO 2 , and H 2 S, which can have serious environmental consequences. These emissions can cause acid rain, acid deposition, and severe air pollution, which can be detrimental to agriculture, human health, and wildlife ( Chen et al ., 2019a ; Sadare et al ., 2017 ; Srivastava, 2012 ; Ansari, 2017 ; Pacheco et al ., 2019 ). As a result of these concerns and in order to implement risk control measures, the Clean Air Act of 1964 was introduced, with subsequent amendments in 1990 and 1999.…”

Biodesulfurization (BDS) of fossil fuels is a promising method for treating the high content of sulfur in crude oils and their derivatives in the future, attributed to its environmental-friendly nature and the technical efficient ability to desulfurize the organosulfur compounds recalcitrant on other techniques. It was found that the bioreaction rate depends on the treated fluid, targeting sulfur compounds, and the microorganism applied. Also, many studies investigated the operation conditions, specificity, and biocatalysts modification to develop BDS efficiency. Furthermore, mathematical kinetics models were formulated to represent the process. In this review, the previous studies are analyzed and discussed. This review article is characterized by a clear picture of all BDS's experimental, industrial, procedural, theoretical, and hypothetical points.
