The green sulfur bacteria are a phylum, Chlorobiota,[4] of obligately anaerobic photoautotrophic bacteria that metabolize sulfur.[5]

Green sulfur bacteria are nonmotile (except Chloroherpeton thalassium, which may glide) and capable of anoxygenic photosynthesis.[5][6] They live in anaerobic aquatic environments.[7] In contrast to plants, green sulfur bacteria mainly use sulfide ions as electron donors.[8] They are autotrophs that utilize the reverse tricarboxylic acid cycle to perform carbon fixation.[9] They are also mixotrophs and reduce nitrogen.[10][11]
