Query: NC_010803:1132500 Chlorobium limicola DSM 245, complete genome
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.
Subject: NC_011026:1681852 Chloroherpeton thalassium ATCC 35110, complete genome
Lineage: Chloroherpeton thalassium; Chloroherpeton; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Chloroherpeton thalassium is a non-filamentous, flexing and gliding green sulfur bacterium isolated from marine sources off the North East coast of the USA in the 1980s. This organism is the most distant member of the green sulfur bacteria and is commonly found in aquatic microbial mats. Chloroherpeton thalassium is distinct from the other green sulfur bacteria in that it grows as a filamentous rod and is capable of gliding motility. Chloroherpeton thalassium is a photolithotroph, obtaining energy by anoxygenic photosynthesis using sulfide or sulfur as the electron donor. The photosynthetic apparatus consist of membrane-bound iron/sulfur reaction center associated with a light absorbing organelle, the chlorosome.
