Chromatium is a genus of photoautotrophic Gram-negative bacteria, also known as purple sulfur bacteria, which are found in water. These bacteria oxidize sulfide to produce sulfur which is deposited in intracellular granules of the cytoplasm. They also couple oxidation of other metals, like iron, in addition to sulfur oxidation.
