Query: NC_008254:3246306 Mesorhizobium sp. BNC1, complete genome
Lineage: Chelativorans; Chelativorans; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This organism was isolated from a mixed-culture enriched from sewage using the chelating agent EDTA (binds divalent cations - ethylenediamine tetraacetic acid) as the sole carbon and nitrogen source. EDTA is often found at toxic waste sites where it is bound to metals and radionuclides, which affects bioremediation efforts. This bacterium is capable of EDTA degradation by itself.
Subject: 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.
