Query: NC_003869:2143892 Thermoanaerobacter tengcongensis MB4, complete genome
Lineage: Caldanaerobacter subterraneus; Caldanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: This organism was originally isolated from a hot spring in Tengcong, China, and is the type strain for the species. Genomic analysis indicates it is similar to Bacillus halodurans and that it has one of the most biased leading strand distribution of genes. Although the organism has not been observed to be motile or to sporulate, it does contain genes for both functions. The bacterium produces acetate and ethanol from glucose and cannot degrade xylan and cellulose.
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.
