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 ...

The green sulfur bacteria, Chlorobiota, are a phylum of obligately anaerobic photoautotrophic bacteria that metabolize sulfur. Green sulfur bacteria are nonmotile (except Chloroherpeton thalassium, which may glide) and capable of anoxygenic photosynthesis. They live in anaerobic aquatic … See more Green sulfur bacteria are gram-negative rod or spherical shaped bacteria. Some types of green sulfur bacteria have gas vacuoles that allow for movement. They are photolithoautotrophs, and use light energy and reduced sulfur … See more Taxonomy • Family Chlorobiaceae Copeland 1956 ["Chlorobacteriaceae" Geitler & Pascher 1925] See more • Anoxic event • Purple sulfur bacteria • Green non-sulfur bacteria • List of bacteria genera See more The majority of green sulfur bacteria are mesophilic, preferring moderate temperatures, and all live in aquatic environments.
