Query: NC_009337:715500 Chlorobium phaeovibrioides DSM 265 chromosome, complete genome
Lineage: Chlorobium phaeovibrioides; Chlorobium; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Nitrogen-fixing photosynthetic bacterium. This organism is unique in its ability to form extracellular sulfur globules from thiosulfate. It is one of the few strains which can use both thiosulfate and tetrathionate as electron donors. Nitrogen fixation.

Lineage: Chlorobium limicola; Chlorobium; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Isolated from Gilroy Hot Spring. The green sulfur bacteria (GSB; Phylum Chlorobi ) are commonly found in illuminated, stratified, and anoxic aquatic environments, sediments, and other sulfide-rich environments including hot springs. This bacterium has been used to model a variety of enzyme and reaction center pathways, including ATP-citrate lyase, isocitrate dehydrogenase, and the reverse Krebs cycle used in photosynthesis. Now called the "reductive carbolic acid cycle", this was found to be the sole carbon dioxide assimilation pathway in other green sulfur bacteria since its discovery.
