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_007517:687276 Geobacter metallireducens GS-15, complete genome
Lineage: Geobacter metallireducens; Geobacter; Geobacteraceae; Desulfuromonadales; Proteobacteria; Bacteria
General Information: First isolated from the Potomac river downstream of Washington, DC, USA in 1987. This organism actively moves towards metal attractants such as iron and manganese oxides, which are insoluble, and produces type IV pili for attachment to the insoluble substrates. Common metal-reducing bacterium. This organism, similar to what is observed in Geobacteria sulfurreducens, couples the oxidation of organic molecules to the reduction of iron by using insoluble Fe (III) as an electron acceptor under anaerobic conditions. This bacterium plays an imporant part of the nutrient cycling in aquatic environments. The cell can also use uranium and plutonium, therefore, this organism and may be important for the bioremediation of contaminated waste sites.
