Desulfobacterium

Desulfobacterium

Desulfobacterium is a genus of sulfate-reducing bacteria. These bacteria are known for their role in the sulfur cycle and are commonly found in anaerobic environments such as marine sediments, wetlands, and sewage treatment plants.

Characteristics

Desulfobacterium species are Gram-negative bacteria that are capable of reducing sulfate to hydrogen sulfide during their metabolic process. This process is crucial in the degradation of organic matter in anaerobic conditions. They are typically rod-shaped and can be motile or non-motile.

Metabolism

Desulfobacterium species utilize a variety of organic compounds as electron donors, including acetate, lactate, and propionate. They play a significant role in the biogeochemical cycling of sulfur and carbon, contributing to the mineralization of organic matter in anaerobic environments.

Ecological Importance

These bacteria are important in the ecology of sedimentary environments where they contribute to the decomposition of organic materials. By reducing sulfate to hydrogen sulfide, they influence the chemistry of their environments and interact with other microbial communities, including methanogens and fermentative bacteria.

Applications

Desulfobacterium species have potential applications in bioremediation due to their ability to degrade pollutants in anaerobic conditions. They are also studied for their role in corrosion of metal structures in marine environments.
