Desulfobacter

Desulfobacter is a type of bacteria that plays a key role in breaking down organic material in environments lacking oxygen, such as deep sediments or marshes. They perform a process called sulfate reduction, where they use sulfate (a mineral compound) to convert organic matter into simpler chemicals, releasing hydrogen sulfide—responsible for the characteristic smell of rotten eggs. These bacteria are important for nutrient cycling in ecosystems and help maintain the balance of chemicals in sediments. They are part of the diverse microbial community that sustains the health of aquatic and terrestrial environments.
