Query: NC_009051:2240480 Methanoculleus marisnigri JR1, complete genome Lineage: Methanoculleus marisnigri; Methanoculleus; Methanomicrobiaceae; Methanomicrobiales; Euryarchaeota; Archaea General Information: Methanogen present in marine and freshwater sediments. Methanoculleus marisnigri was first isolated from sediment from the Black Sea, but has also been identified in freshwater sediments. This organism can use hydrogen, formate, and secondary alcohols, such as propanol and butanol, for methanogenesis.

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.
