Lineage: Methanosphaera stadtmanae; Methanosphaera; Methanobacteriaceae; Methanobacteriales; Euryarchaeota; Archaea
General Information: Isolated from human feces. Methanogen that uses methanol and hydrogen to produce methane. This organism produces methane from methanol and hydrogen unlike most methanogens that use carbon dioxide and hydrogen.
Subject: NC_012881:3727150 Desulfovibrio salexigens DSM 2638, complete genome
Lineage: Desulfovibrio salexigens; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: Isolation: mud in British Guyana; Temp: Mesophile; Temp: 37 C; Habitat: Mud. Desulfovibrio are sulfate-reducing bacteria which reduce sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. These organisms typically grow anaerobically, although some can tolerate oxygen, and they utilize a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making these organisms of interest as bioremediators. These organisms are responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.
