Query: NC_012632:1212780 Sulfolobus islandicus M.16.27 chromosome, complete genome
Lineage: Sulfolobus islandicus; Sulfolobus; Sulfolobaceae; Sulfolobales; Crenarchaeota; Archaea
General Information: This strain was isolated from a hot spring on the Kamchatka Penninsula, in the Russian Far East. Hyperthermophilic acidophilic sulfur-metabolizing archeon. Sulfolobus islandicus is a thermo-acidophilic archeae commonly identified in hot, acidic sulfur springs. This organism can grow both chemoautotrophically, using sulfur or hydrogen sulfide, and heterotrophically. S. islandicus can play host to a number of plasmids and viruses which may be useful in developing tools for genetic analysis. In addition, Sulfolobus islandicus isolates from different areas in Russia, Iceland, and the United States have been shown to be genetically distinct from each other making this organism useful for comparative analysis.
Subject: 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.
