Rhodobacter sphaeroides is a kind of bacteria belonging to the purple bacteria, a group of bacteria that can produce energy through photosynthesis.

R. Sphaeroides live in deep lakes. To survive with such low light, the proteo-bacteria have devloped a diverse system of energy binding processes. For example, the kind capable of photosynthesis, lithotrofie and both aerobic and anaerobic oxidation. Furthermore, for example, he also bind nitrogen [1].

R. Sphaeroides is often used for research into photosynthesis. This has probably one of the best researched photo synthesis systems of all species.

The species also has many scientific interest because of its unique genetic complexity. It has two chromosomes, one long and one small round. Het kleine chromosoom heeft veel minder informatiedichtheid dan het grote chromosoom, en dient mogelijk als een soort reservoir dat het mogelijk maakt voor het DNA om de nodige veranderingen te ondergaan zonder dat de soort gevaar loopt. [2] . The small chromosome has much less than the big informatiedichtheid chromosome, and serves as a kind of possible reservoir that makes it possible for the DNA to make the necessary changes without having to undergo the kind of danger.
