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_012781:4065 Eubacterium rectale ATCC 33656, complete genome

Lineage: Eubacterium rectale; Eubacterium; Eubacteriaceae; Clostridiales; Firmicutes; Bacteria

General Information: Eubacterium rectale ATCC 33656 was isolated from human feces. This genus has been isolated as normal flora from feces, rumen, and periodontal tissue. Eubacterium spp. are thought to play a beneficial role in maintaining the normal ecology of the large intestine, in part by producing chemicals like butyric acid which act to inhibit the growth of other bacteria. These organisms are occasionally isolated from wounds and abscesses and may be an opportunistic pathogen. This genus has also been isolated from sewage and soil.
