Query: NC_018531:3625810 Arthrobacter sp. Rue61a chromosome, complete genome
Lineage: Arthrobacter; Arthrobacter; Micrococcaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Bacteria of the genus Arthrobacter are ubiquitous in the environment. They are characterized by nutritional versatility and pronounced resistance to desiccation, long-term starvation, toxic compounds, oxidative stress, and other environmental stress conditions. Arthrobacter nitroguajacolicus strain Rü61a was previously isolated from sludge of the biological wastewater treatment plant of a coal tar refining company, based on its ability to utilize quinaldine (2-methylquinoline) as source of carbon and energy.
Subject: NC_007517:1676604 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.
