Abstract

This article focuses on the sulfur metabolism of Rhodococcus bacteria and its role in biodesulfurization (BDS), an environmentally friendly microbial process for removing refractory organosulfur compounds from fossil fuels. It details the 4S pathway—mediated by the dszABC operon—as the primary mechanism for dibenzothiophene (DBT) desulfurization in Rhodococcus, including its enzymatic steps, regulatory factors, and challenges such as substrate inhibition and limited industrial efficiency. The review also examines how sulfur metabolism pathways and transcriptional regulation influence BDS efficiency, highlighting recent genetic engineering strategies, including CRISPR/Cas-based tools, to optimize both the 4S pathway and sulfur metabolic flux. These insights aim to advance the industrial application of BDS for producing zero-sulfur fuels.
