Chromatium okenii is a Gram-negative bacterium found in water. It belongs to the Purple sulfur bacteria. These bacteria are capable of photosynthesis and use Hydrogen sulfide (HS) as an electron donor for CO reduction and so do not produce oxygen. This type of photosynthesis is called anoxygenic photosynthesis.
