Ultrasound assisted biodesulfurization of liquid fuel using free and immobilized cells of Rhodococcus rhodochrous MTCC 3552: A mechanistic investigation

Mechanistic analysis of ultrasound assisted enzymatic desulfurization of liquid fuels using horseradish peroxidase

“…Therefore, the DBT molecules remain predominantly in organic phase and are exposed only to the transient cavitation activity in this phase (and not in aqueous phase). This is in contrast to our earlier study of microbial desulfurization (Bhasarkar et al, 2015). In microbial desulfurization, the reactions occur inside the microbial cells, which are present in aqueous medium.…”

“…This requires transfer of DBT molecules from organic to aqueous phase. For this purpose, the surfactant b-CD was used by Bhasarkar et al (2015), which forms a complex with DBT enhancing its solubility in aqueous phase. Thus, the DBT molecules are exposed to cavitation activity in both organic and aqueous phase, and hence, Bhasarkar et al (2015) have taken into account simulations of cavitation bubble dynamics in both aqueous and organic phases.…”

“…In addition, HDS is difficult to remove heterocyclic organosulfur such as benzothiophene (BT), dibenzothiophene (DBT) and their derivatives. Due to these reasons, many groups [7][8][9][10] have been engaged in the exploitation of non-HDS technologies for transportation fuels, including extraction [11][12] , oxidation [13][14] , adsorption [15][16] , biological desulfurization [17][18] and others [19][20] .…”

Biodegradation of dibenzothiophene and its application in the production of clean coal

“…However, ultrasonication had a negative effect on the surfactant activity, which was used to increase mass transfer of DBT between organic and aqueous phase. The desulphurization efficiency was higher in case of free cells (77% DBT reduction) and simultaneous use of surfactant, β-cyclodextrin [122].…”
