Lineage: Amoebophilus asiaticus; Amoebophilus; Amoebophilaceae; Cytophagales; Bacteroidetes; Bacteria
General Information: Candidatus Amoebophilus asiaticus 5a2 is an obligate endosymbiont found in Acanthamoeba sp. TUMSJ-321. This organism is a member of the highly diverse bacterial phylum Bacteroidetes which includes the endosymbiont lineages represented by the sister taxa Candidatus A. asiaticus and Candidatus Cardinium hertigii, a symbiont of arthropods.
Subject: NC_007517:2165657 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.
