Query: NC_009465:171000 Candidatus Vesicomyosocius okutanii HA, complete genome
Lineage: Calyptogena okutanii thioautotrophic gill symbiont; sulfur-oxidizing symbionts; ; sulfur-oxidizing symbionts; Proteobacteria; Bacteria
General Information: This strain was collected off Hatsushima island in Sagami Bay, Japan. Calyptogena okutanii (deep-sea clam) thioautotrophic gill symbiont. The bivalve marine species Calyptogena okutanii depends on sulfur-oxidizing symbiotic bacteria housed in its gill tissues for its sole nutritional support. The symbiont is transmitted vertically between generations via the clam's eggs. This anaerobic symbiosis oxidizes hydrogen sulfide as an energy source and fixes carbon dioxide into organic compounds.
Subject: NC_011026:1284966 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.
