Query: NC_010424:14657 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_011004:5520771 Rhodopseudomonas palustris TIE-1, complete genome
Lineage: Rhodopseudomonas palustris; Rhodopseudomonas; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain was isolated from an iron-rich microbial mat from School Street Marsh in Woods Hole, MA, USA. It grows photoautotrophically with Fe(II), H2, or thiosulfate as the electron donor, photoheterotrophically with a variety of organic carbon sources and chemoheterotrophically in the dark. This organism has a diverse metabolism and is capable of growth using light, inorganic, or organic compounds as energy sources and carbon dioxide or organic compounds as carbon sources. Commonly found in soil and water environments this bacterium is also capable of degrading a wide range of toxic organic compounds, and may be of use in bioremediation of polluted sites. The bacterium undergoes differentiation to produce a stalked nonmotile cell and a motile flagellated cell. In the presence of light, this bacterium produces a number of intracellular membranous vesicles to house the photosynthetic reaction centers.
