Query: NC_013967:2760473 Haloferax volcanii DS2 chromosome, complete genome
Lineage: Haloferax volcanii; Haloferax; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea
General Information: Haloferax volcanii DS2 was isolated from bottom sediments from the Dead Sea. Halophilic archaeon. This organism is similar to halobacteria and was originally classified in that genus. It has an optimum requirement for sodium chloride in the 1.7-2.5 molar which is half that generally associated with other halobacterium species.
Subject: NC_011958:1031592 Rhodobacter sphaeroides KD131 chromosome 2, complete genome
Lineage: Rhodobacter sphaeroides; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to grow using photosynthesis, chemosynthesis, and usually can grow under both anaerobic and aerobic conditions. The most extensively studied bacteria with regards to its photosynthetic capabilities which includes the structure, function and regulation of its photosynthetic membranes, its mechanisms of CO2 and nitrogen fixation, cytochrome diversity and its electron transport systems. It can grow aerobically and anaerobically in the light and anaerobically in the dark. It produces an intracytoplasmic membrane system consisting of membrane invaginations where the light harvesting complexes (LH1 and LH2) and the reaction center are synthesized. Furthermore, it has the ability to detoxify metal oxides and oxyanions and hence has a role in bioremediation.
