Subject: NC_008789:942309 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.
