“…There was almost a 99% decrease in total sulfur level of DBT at 40 • C in 24 h. About 59% of total sulphur was removed from Liaoning crude oil after 72 h treatment. Various studies of % sulphur removal from petroleum distillates by BDS techniques are summarized in Table 2 and Figure 2, at optimum temperatures and DBT concentrations using different microorganisms [124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139]. The microorganisms are abbreviated as follow; Gordonia alkanivorans RIPI90A (GAR 190A), Gordonia alkanivorans strain 1B (GAS 1B), Rhodococcus erythropolis IGTS8 (RE IGTS8 …”

Sulfur oxide (SO 2 ) and hydrogen sulfide (H 2 S) are considered as one of the major air pollutants in the world today. In addition, high sulfur levels in petroleum distillates can promote the deactivation of catalysts through poisoning in fluidized catalytic cracking (FCC) during hydrocracking of the heavy distillates to lighter ones. The presence of high sulfur-containing compounds in the process streams could cause corrosion of piping and fittings and equipment, thereby damaging the pipelines and leading to air emissions of sulfur-containing compounds, which are undesirable for mankind and his environment. In many cases, a large quantity of SO x is released into the atmosphere when petroleum distillates that contain substantial amount of sulphur-containing compounds are used as fuel and combust. In this article, a short overview of different desulfurization methods that are employed to remove sulfur from petroleum distillates is provided. In particular, the review concentrates on biodesulfurization technique. In addition, this article intends to provide its readers current status of biodesulfurization (BDS). It critically analyses the trend in the development of the technology to showcase its strength and weakness that could pave a way for future opportunities. Approaches that are suitable to remediate sulfur-contaminated environment are discussed as well. Lastly, speculations on future directions or opportunities that require exploration are provided as a way of provoking the thoughts of researchers in this field.

“…43 [38,39]. The methods for bacterial cells immobilization considered the cells entrapment and cells adsorption [26,33]. However, the adsorption of cells on polymer support require more complex chemical and biochemical analysis that also consider non-electrostatic interactions and bacterial hydrophobic behaviour [38].…”

“…Biomodification of chemical supports using cells immobilization via adsorption increases the interaction between reactants present in two-phase systems [26][27][28]. These materials must be inert to biological attack, insoluble in the growth media and non-toxic to microbial cells, hence polymeric supports are proper choices, sorption capacity, chemical resistance and mechanical strength of polymer support and solubility parameter is the main factor in the selection of a polymer support [29][30][31].…”

Abstract:A new biodesulphurization method has been considered using Pseudomonas aeruginosa supported on polyethylene (PE) for biodesulphurization (BDS) of thiophene as an aromatic sulphur model compound of crude oils. Also the biodegradation of thiophene has been modified in the presence of potassium hexacyanoferrate(III) as a terminal electron acceptor to approach the maximum biodesulphurization efficiency. The obtaining results according to UV-Spectrophotometry at 240 nm, 83.3% of thiophene at the primary concentration of 50 mg/dm 3 , pH = 7, by 0.5 g of biocatalyst in 37°C after 4 h of contact time has been removed. The bacterial cells exhibited a greater and faster biodegradation in the presence of potassium hexacyanoferrate(III) and 94.8% of thiophene has been removed after 3 h of contact time. Kinetic study predicted chemisorption of thiophene on the surface of the biocatalyst, as it followed the pseudo-second-order rate equation. Morphology and surface functional groups of the biocatalyst have been investigated by SEM and FT-IR, respectively.

“…Although this process is plenty useful for removing the element from aliphatic and some aromatic compounds, it does not have enough influence on some cyclic molecules such as dibenzothiophene and its alkylated derivatives. On the other hand, HDS requires high temperature and high pressure which cost a huge budget [3][4][5]. Biodesulfurization has been the promising technology to compensate the weak points of HDS.…”
