Query: NC_010424:214640 Candidatus Desulforudis audaxviator MP104C, complete genome
Lineage: Desulforudis audaxviator; Desulforudis; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is a gram positive sulfate reducing bacteria identified in fracture water from a borehole at a depth of 2.8 km in a South African gold mine. Water from these boreholes is very old (low-biodiversity fracture water), suggesting that these bacteria have been isolated from the Earth's surface for as much as several million years.
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.
