Query: NC_008789:707916 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_007298:2947200 Dechloromonas aromatica RCB, complete genome
Lineage: Dechloromonas aromatica; Dechloromonas; Rhodocyclaceae; Rhodocyclales; Proteobacteria; Bacteria
General Information: This strain was enriched as a hydrocarbon-oxidizing chlorate-reducer from the Potomac River, Maryland, USA. This organism is the first one to have the capability of benzene oxidation in pure anaerobic culture by coupling it to nitrate reduction which is of importance due to the anaerobic environments often found in bioremediation projects. It can reduce perchlorate and chlorate to chloride. This organism may be used for bioremediation as it can oxidize aromatic hydrocarbon compounds, including benzene, in the absence of oxygen. Benzene is an important pollutant, and is used in many manufacturing processes and is a component of diesel fuel.
