Query: NC_002936:1319266 Dehalococcoides ethenogenes 195, complete genome

Lineage: Dehalococcoides mccartyi; Dehalococcoides; Dehalococcoidaceae; Dehalococcoidales; Chloroflexi; Bacteria

General Information: Dechlorinates tetrachloroethene. This organism was isolated from environments contaminated with organic chlorinated chemicals such as tetrachloroethene (PCE) and trichloroethane (TCE), common contaminants in the anaerobic subsurface. There are at least 15 organisms from different metabolic groups, halorespirators, acetogens, methanogens and facultative anaerobes, that are able to metabolize PCE. Some of these organisms couple dehalogenation to energy conservation and utilize PCE as the only source of energy while others dehalogenate tetrachloroethene fortuitously. This non-methanogenic, non-acetogenic culture is able to grow with hydrogen as the electron donor, indicating that hydrogen/PCE serves as an electron donor/acceptor for energy conservation and growth. This organism can only grow anaerobically in the presence of hydrogen as an electron donor and chlorinated compounds as electron acceptors. Dehalococcoides ethenogenes is typically found at sites contaminated with chlorinated solvents, and have been independently isolated in dozens of sites across the USA.

Subject: NC_012881:3362955 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.
