Query: NC_012988:32996 Methylobacterium extorquens DM4, complete genome
Lineage: Methylobacterium extorquens; Methylobacterium; Methylobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Methylobacterium extorquens DM4 was isolated from soil contaminated with halogenated (chlorine-containing) hydrocarbons. This organism is able to use dichloromethane as a sole carbon and energy source. Dichloromethane, an industrial solvent, is toxic and carcinogenic. This compound is water soluble and can easily contaminate groundwater. Methylobacterium chloromethanicum was isolated from soil at a petrochemical factory in Tatarstan, Russia. This organism is able to grow using chloromethane as the sole carbon and energy source.
Subject: NC_007517:2820909 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.
