Thermophilic eubacteria are suggested to have been among the earliest bacteria. [ 3 ] Thermophiles are found in various geothermally heated regions of the Earth , such as hot springs like those in Yellowstone National Park (see image) and deep sea hydrothermal vents , as well as decaying plant matter, such as peat bogs and compost .
Changes inherited over time via DNA have allowed these organisms to build up various resistances and immunities to the volatile nature of their homes. [2] It is these traits that have scientists so fixated on extremophiles because the genes that allow for said abilities can be taken from extremophiles and used in various biotechnical processes.
Extremophiles that prefer cold environments are termed psychrophilic, those preferring warmer temperatures are termed thermophilic or thermotropic and those thriving in extremely hot environments are hyperthermophilic. A genome-wide computational approach has been designed by Zheng, et al. to classify bacteria into mesophilic and thermophilic. [3]
A thermoacidophile is an extremophilic microorganism that is both thermophilic and acidophilic; i.e., it can grow under conditions of high temperature and low pH. [1] The large majority of thermoacidophiles are archaea (particularly the Thermoproteota and "Euryarchaeota") or bacteria, though occasional eukaryotic examples have been reported.
The oxidation of reduced sulfur compounds is performed exclusively by Bacteria and Archaea.All the Archaea involved in this process are aerobic and belong to the Order Sulfolobales, [19] [20] characterized by acidophiles (extremophiles that require low pHs to grow) and thermophiles (extremophiles that require high temperatures to grow).
The paper and the chapter in Bergey's manual were authored by several authors including the microbiologists Karl Stetter and Carl Woese. [2]The Neo-Latin feminine name "thermotoga" means "the hot outer garment", being a combination of the Greek noun θέρμη (therme, heat) [7] or more correctly the adjective θερμός, ή, όν (thermos, e, on, hot) [8] and the Latin feminine noun toga ...
When PopCap isn't busy hopping on the casino game bandwagon, it's turning non-gamers into strategy game gurus without them knowing. Now that's talent. During Game Developers Conference in San ...
Zombies were designed to move in the current linear five- and six-lane system in the final game, [24] [25] allowing the enemy zombies to interact with the defensive plants, a refinement in the game that Fan felt worked as a unique gameplay mechanic to make Plants vs. Zombies stand out in the tower defense genre amongst other tower defense games ...
