Sulfate-reducing bacteria break down a large proportion of the organic carbon in the oxygen-free zones of Earth, and in the seabed in particular. Among these important microbes, the Desulfobacteraceae family of bacteria stands out because its members are able to break down a wide variety of compounds—including some that are poorly degradable—to their end product, carbon dioxide (CO2).
