Hyperthermophilic Microorganisms and USP Hot Water Systems
José E. Martinez, MS-MT, is a senior validation scientist and validation project manager at Amgen Manufacturing Ltd., tel. 787.656.1011, [email protected]. y definition, thermophiles love heat. In fact, thermophiles thrive at temperatures that will kill most other forms of life. Regular thermophiles (referred to as thermophiles in this article) are organisms that live at temperatures 45 C and h...
متن کاملHydrothermal vent ecosystems and representative hyperthermophilic microorganisms
One of the most spectacular events of the present century, concerning all biological and environmental disciplines, was the discovery of deep-sea hydrothermal vents around the Galapagos Islands, during the late 1970s. This remarkable scientific accomplishment was achieved thanks to the extensive work carried out by oceanographers and geologists. A significant role in terms of scientific support...
متن کاملAcetate oxidation coupled to Fe(iii) reduction in hyperthermophilic microorganisms.
No hyperthermophilic microorganisms have previously been shown to anaerobically oxidize acetate, the key extracellular intermediate in the anaerobic oxidation of organic matter. Here we report that two hyperthermophiles, Ferroglobus placidus and "Geoglobus ahangari," grow at 85 degrees C by oxidizing acetate to carbon dioxide, with Fe(III) serving as the electron acceptor. These results demonst...
متن کاملValidation of a Hypothesis: Colonization of Black Smokers by Hyperthermophilic Microorganisms
Newly erupted black smokers (hydrothermal vent chimneys) are sterile during their formation, but house hyperthermophilic microorganisms in substantial amounts in later stages. No direct experimental data exist by which mechanisms hyperthermophiles colonize newly erupted black smokers, but a scenario was proposed recently how this might happen. Here we combine high temperature light microscopy w...
متن کاملGrowth of thermophilic and hyperthermophilic Fe(III)-reducing microorganisms on a ferruginous smectite as the sole electron acceptor.
Recent studies have suggested that the structural Fe(III) within phyllosilicate minerals, including smectite and illite, is an important electron acceptor for Fe(III)-reducing microorganisms in sedimentary environments at moderate temperatures. The reduction of structural Fe(III) by thermophiles, however, has not previously been described. A wide range of thermophilic and hyperthermophilic Arch...
