Desulfurobacteriaceae

Desulfurobacteriaceae is a family of bacteria that belongs to the phylum Aquificae. This family of bacteria is known for its unique ability to reduce sulfate to sulfide, a process known as sulfate-reducing.

Taxonomy

The family Desulfurobacteriaceae is classified under the phylum Aquificae, which is a group of bacteria that are known for their ability to survive in extreme thermophilic conditions. The family Desulfurobacteriaceae includes the following genera:

• Desulfurobacterium
• Thermovibrio
• Balnearium
• Phorcysia

Characteristics

Members of the Desulfurobacteriaceae family are anaerobic bacteria that are capable of reducing sulfate to sulfide. They are typically found in hydrothermal vents and other extreme environments. These bacteria are thermophilic, meaning they thrive in high-temperature environments.

Metabolism

Desulfurobacteriaceae bacteria are known for their unique metabolic process. They are chemoautotrophic, meaning they obtain energy by oxidizing inorganic substances. Specifically, these bacteria are capable of reducing sulfate to sulfide, a process known as sulfate-reducing. This process is significant as it plays a role in the sulfur cycle, one of the major biogeochemical cycles on Earth.

Ecological Significance

Desulfurobacteriaceae bacteria play a crucial role in the sulfur cycle. By reducing sulfate to sulfide, they contribute to the recycling of sulfur in the environment. This process is particularly important in anaerobic environments, where the reduction of sulfate is a major pathway for the oxidation of organic matter.
