Query: NC_007426:205390 Natronomonas pharaonis DSM 2160, complete genome

Lineage: Natronomonas pharaonis; Natronomonas; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea

General Information: Isolated from Lake Gabara in Egypt. Extreme haloalkaliphilic archeon. Natronomonas pharaonis is able to survive at high salt and pH conditions which results in limited nitrogen availability through ammonium. In order to compensate for this, Natronomonas pharaonis has developed three systems to promote nitrogen assimilation: direct uptake of ammonia, uptake of nitrate, and uptake of urea. Another problem with high pH environments is the use of a proton gradient for the generation of ATP, which other alkaliphiles have adapted to by substitution of sodium ions for protons. However, this organism utilizes protons for ATP generation as determined by experimental data.

Subject: 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.
