Green sulfur bacteria

WebChlorobium is a genus of green sulfur bacteria.They are photolithotrophic oxidizers of sulfur and most notably utilise a noncyclic electron transport chain to reduce NAD+. Photosynthesis is achieved using a Type 1 Reaction Centre using bacteriochlorophyll (BChl) a.Two photosynthetic antenna complexes aid in light absorption: the Fenna-Matthews … WebThe electron transport chain of green sulfur bacteria — such as is present in the model organism Chlorobaculum tepidum — uses the reaction center bacteriochlorophyll pair, P840. When light is absorbed by the reaction center, P840 enters an excited state with a large negative reduction potential, and so readily donates the electron to ...
