Green sulfur bacteria are nonmotile (except Chloroherpeton thalassium, which may glide) and capable of anoxygenic photosynthesis.In contrast to plants, green sulfur bacteria mainly use sulfide ions as electron donors.They are autotrophs that utilize the reverse tricarboxylic acid cycle to fix carbon dioxide. Green sulfur bacteria have been found in depths of up to 145m in the Black Sea, with low light availability.
