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 compounds as the electron source. [12] Electron donors include H 2, H 2 S, S.
Chlorobium 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.
A chlorosome is a photosynthetic antenna complex found in green sulfur bacteria (GSB) and many green non-sulfur bacteria (GNsB), together known as green bacteria. [2] They differ from other antenna complexes by their large size and lack of protein matrix supporting the photosynthetic pigments.
These bacteria are facultative aerobic. [3] They generally use chemotrophy when oxygen is present and switch to light-derived energy when otherwise. Most species are heterotrophs, but a few are capable of photoautotrophy. [2] The order can be divided into two suborders. Chloroflexineae ("Green FAP", "green non-sulfur bacteria") is the better ...
Like all other green sulfur bacteria, P. aestuarii gets its energy through a process called anoxygenic photosynthesis.Their major pigment is bacteriochlorophyll c, giving the cultures a green appearance; however, as they age, cultures can become a dirty green/brown, or white with build-up of elemental sulfur.

The name "Chloroflexi" is a Neolatin plural of "Chloroflexus", which is the name of the first genus described. The noun is a combination of the Greek chloros (χλωρός) [2] meaning "greenish-yellow" and the Latin flexus (of flecto) [3] meaning "bent" to mean "a green bending". [4]
Chlorobaculum tepidum, previously known as Chlorobium tepidum, [1] is an anaerobic, thermophilic green sulfur bacteria first isolated from New Zealand. [2] Its cells are gram-negative and non-motile rods of variable length. They contain chlorosomes [3] and bacteriochlorophyll a and c. [4]
