Lineage: Thioalkalimicrobium cyclicum; Thioalkalimicrobium; Piscirickettsiaceae; Thiotrichales; Proteobacteria; Bacteria
General Information: Isolation: Water; USA, California, Lake Mono. This organism is a sulfur-oxidizing bacterium isolated from highly alkaline soda lakes. These bacteria have a pH optimum of 10 and are able to oxidize sulfide, thiosulfate and tetrathionate.
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.
