Query: NC_008701:1582839 Pyrobaculum islandicum DSM 4184, complete genome
Lineage: Pyrobaculum islandicum; Pyrobaculum; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: Hyperthermophilic anaerobe. Pyrobaculum islandicum was isolated from water from a geothermal power plant in Iceland. This organism is able to grow lithotrophically and organotrophically using hydrogen or organic matter as the electron donors and sulfur, sulfite, and thiosulfate as electron acceptors.
Subject: NC_004463:1520303 Bradyrhizobium japonicum USDA 110, complete genome
Lineage: Bradyrhizobium diazoefficiens; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain was isolated from Glycine hispida in 1959 in Florida, USA, and has been widely studied because of its superior symbiotic nitrogen fixation with soybeans as compared to other strains. This strain contains a 681 Kb symbiosis island that contains genes for nitrogen fixation and root nodule formation. The chromosome also contains genes resembling those of type III and IV secretion systems.
