Query: NC_003413:128228 Pyrococcus furiosus DSM 3638, complete genome
Lineage: Pyrococcus furiosus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This strain was isolated from a shallow marine solfataric (volcanic area that gives off sulfuric gases) region at Vulcano Island, Italy. This organism is a strictly anaerobic, hyperthermophilic archaeon. Growth occurs at temperatures between 67 and 103 degrees C, with optimal growth at 100 degrees C and a pH of 7.0. This organism is highly motile due to a bundle of flagella.
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.
