The increasing emission of sulfur-containing compounds has become a critical factor restricting ecological and environmental security and the sustainable resource utilization. Biological desulfurization technology, relying on the sulfur metabolic pathways of desulfurization microorganisms, enables the efficient conversion of sulfur-containing pollutants and the recovery of sulfur resources under mild conditions, offering both environmental benefits and economic potential. This review systematically summarized the classification and functional characteristics of desulfurization microorganisms, with emphasis on the 4S pathway, the Kodama pathway, and related metabolic modes of organic sulfur-desulfurizing bacteria, as well as the sulfate reduction and sulfur oxidation mechanisms of inorganic sulfur-desulfurizing bacteria. On this basis, the advances in engineering applications in the fields of industrial gas purification, sludge and wastewater treatment, livestock and poultry manure management, domestic waste and agriculture were summarized, and the key environmental factors and carbon source regulation mechanisms affecting desulfurization efficiency were analyzed. Furthermore, the main bottlenecks currently faced by biological desulfurization technology were summarized from the aspects of strain performance, reaction kinetics, mass transfer enhancement, and process stability, and research directions for system enhancement through functional microbial community construction, reactor optimization, and intelligent regulation were proposed. This review aims to provide theoretical references and technical insights for the deepening of biological desulfurization mechanisms and efficient engineering applications.
