Query: NC_007722:55558 Erythrobacter litoralis HTCC2594, complete genome

Lineage: Erythrobacter litoralis; Erythrobacter; Erythrobacteraceae; Sphingomonadales; Proteobacteria; Bacteria

General Information: This strain was collected from the Sargasso Sea at a depth of 10 meters. Phototrophic bacterium. Organisms in this aerobic phototrophic genus are found in marine environments. Members of this group produce bacteriochlorophyll a, which is normally found in anaerobic organisms. One theory to explain this is that the anoxygenic photosynthetic gene cluster was acquired by these organisms via lateral gene transfer. Although they require an organic carbon substrate for growth, they are able to supplement a significant fraction of their metabolic requirements with photosynthetically derviced energy. This species was isolated from a marine cyanobacterial mat. Although they require an organic carbon substrate for growth, they are able to supplement a significant fraction of their metabolic requirements with photosynthetically derviced energy. The presence of the carotenoids bacteriorubixanthinal and erythroxanthin sulfate give this organism a reddish color.

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.
