Query: NC_008789:350650 Halorhodospira halophila SL1, complete genome
Lineage: Halorhodospira halophila; Halorhodospira; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria
General Information: Halorhodospira halophila SL1 was isolated from salt lake mud. Sulfur-oxidizing extreme halophile. This organism, formerly Ectothiorhodospira halophila is alkaliphilic, phototrophic, halophile. This is one of the most halophilic eubacteria known, and produces organic solutes such as glycine betaine, ectoine, and trehalose to balance the osmotic pressure. This organism oxidizes sulfide to sulfur, which is deposited outside the cell and further oxidized to sulfate. This organism also produces a blue light sensor called photoactive yellow protein which is involved in signal transduction.
Subject: NC_009050:811358 Rhodobacter sphaeroides ATCC 17029 chromosome 2, complete sequence
Lineage: Rhodobacter sphaeroides; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: A photosynthetic bacterium useful in bioremediation. Anoxygenic photosynthesis, Carbon fixation, Nitrogen fixation. 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. 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.
