Description

Alcanivorax borkumensis [1F]

Chromatium is a gram negative bacteria found in marine environments. They tend to be straight rod shaped or even slightly curved rods. These bacteria belong to the purple photosynthetic sulfur bacteria that oxidize sulfide into sulfur which is deposited in intracellular granules in their cytoplasm.

They grow in the presence of light under anaerobic conditions. They can grow on an inorganic medium using CO2 as the sole carbon source in the presence of reduced inorganic sulfur.
