Abstract: Sulfur exists widely in fossil fuel. The combustion of fossil fuels has led to the release of sulfur dioxide into the atmosphere, which has resulted in the deterioration of the quality of environment. With the indepth understanding of biochemistry and microbial ecology, biodesulfurization has been highly concerned due to the advantages of high efficiency, energy saving and low power consumption in environmental protection industry. This paper reviewed the type of desulfurization microorganisms and their mutual relations, discussed the situation and prospects of the application of genetic engineering technology in biological desulferization, so as to provide references for biological desulfurization research in the future.

Key words: biological desulfurization, microorganism, genetic engineering
