Query: NC_003869:45560 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.

General Information: This is the type strain (DSM 4304) of the Archaeoglobales, and was isolated from a geothermally heated sea floor at Vulcano Island, Italy. Doubling time is four hours under optimal conditions. The organism is an autotrophic or organotrophic sulfate/sulfite respirer. An additional distinguishing characteristic is blue-green fluorescence at 420 nm. This bacterium is the first sulfur-metabolizing organism to have its genome sequence determined. Growth by sulfate reduction is restricted to relatively few groups of prokaryotes; all but one of these are Eubacteria, the exception being the archaeal sulfate reducers in the Archaeoglobales. These organisms are unique in that they are only distantly related to other bacterial sulfate reducers, and because they can grow at extremely high temperatures. The known Archaeoglobales are strict anaerobes, most of which are hyperthermophilic marine sulfate reducers found in hydrothermal environments. High-temperature sulfate reduction by Archaeoglobus species contributes to deep subsurface oil-well 'souring' by iron sulfide, which causes corrosion of iron and steel in oil-and gas-processing systems.
