Query: NC_006138:1921424 Desulfotalea psychrophila LSv54, complete genome
Lineage: Desulfotalea psychrophila; Desulfotalea; Desulfobulbaceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: This organism was isolated from marine sediments off of the coast of Svalbard, and can grow at temperatures as low as -1.7 degrees C. Sulfate-reducing bacterium. This organism grows on more complex organic compounds such as acetate, propionate, butyrate, lactate as well as by using simpler compounds such as hydrogen. This organism is an important part of global biogeochemical cycling of carbon and other nutrients.
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.
