Query: NC_014219:25845 Bacillus selenitireducens MLS10 chromosome, complete genome
Lineage: Bacillus selenitireducens; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Isolation: Anoxic muds of Mono Lake California; Country: USA; Temp: Mesophile; Habitat: Fresh water. Bacillus selenitireducens MLS-10 was isolated from alkaline, hypersaline, arsenic-rich mud from Mono Lake, California. This organism can reduce arsenate, selenate, and selenite, making it a potential bioremediation agent. Bacillus selenitireducens produces intracellular and extracellular granules of elemental selenium when grown on selenite. The respiratory arsenate reductase has been purified, and is able to function at high pH and alkalinity.
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.
