Query: NC_012815:1465670 Bifidobacterium animalis subsp. lactis DSM 10140, complete genome Lineage: Bifidobacterium animalis; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria General Information: Bifidobacterium animalis subsp. lactis (strain DSM 10140 / JCM 10602 / LMG 18314) is an anaerobic Gram-positive lactic acid bacterium commonly found in the guts of healthy humans and has been identified in the infant gut biota, particularly in ileal, fecal, and mucosal samples. Some strains of B. animalis subsp. lactis are able to survive in the GIT, to adhere to human epithelial cells in vitro, to modify fecal flora, to modulate the host immune response, or to prevent microbial gastroenteritis and colitis.

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.
