Abstract

Thiophene, benzothiophene and dibenzothiophene are the main organic sulfur compounds in crude oil, which reduce the quality of crude oil. Previous studies have shown that biodesulfurization (BDS) is the most efficient method for the separation of complex organic sulfur compounds from crude oil. BDS is performed at ambient pressure and temperature with excellent selectivity, leading to reduced energy cost, low emissions of CO₂ and lack of production of unfavorable by-products. In this review study, the advantages and disadvantages of BDS compared to other processes, the performance of various microorganisms in the removal of complex sulfur compounds, environmental impacts, and biodesulfurization kinetics were thoroughly discussed. Also, different mechanisms of biodesulfurization process and their pathways in removing sulfur compounds were investigated. Moreover, the utilization of genetic engineering to improve biodesulfurization efficiency was studied. According to previous studies, the Bintulu oil field in Malaysia and the Boscan oil field in Venezuela have the lowest (0.03 %) and the highest sulfur content (5.7 %), respectively. Also, some microorganisms such as Mycobacterium goodie X7B, Rhodococcus erythropolis XP, Rhodococcus sp. ECRD-1, and Gordonia alkanivorans have shown significant biodesulfurization efficiency. In general, the integration of BDS and hydrodesulfurization processes is recommended as an efficient and environmentally friendly process in removing complex sulfur compounds.

期刊介绍： Process Biochemistry is an application-orientated research journal devoted to reporting advances with originality and novelty, in the science and technology of the processes involving bioactive molecules and living organisms. These processes concern the production of useful metabolites or materials, or the removal of toxic compounds using tools and methods of current biology and engineering. Its main areas of interest include novel bioprocesses and enabling technologies (such as nanobiotechnology, tissue engineering, directed evolution, metabolic engineering, systems biology, and synthetic biology) applicable in food (nutraceutical), healthcare (medical, pharmaceutical, cosmetic), energy (biofuels), environmental, and biorefinery industries and their underlying biological and engineering principles.
