Thermophiles
Thermophiles are micro-organisms that live and grow in extremely hot environments. They are a type of extremophile (an organism that thrives in physically or geochemically extreme conditions). They can be grouped into procaryotes, and are classified in Archaea. They thrive at high temperatures, between 45˚C and 122˚C.
Thermophiles are usually found in various geothermally heated regions of the Earth, such as hot springs like those in Yellowstone National Park and deep sea hydrothermal vents. They also live in environments that create heat themselves, such as a pile of compost of rubbish landfills.
Thermophiles contain enzymes that can function at high temperatures. Thermophiles are classified into obligate (require high temperatures) and facultative (can also thrive at lower temperatures as well as high). Thermococcus celer is an example of thermophilic Archaea species.
Halophiles
Halophiles are organisms that live in high salt concentrations. They are a type of extremophile organism. The name comes from the Greek word for "salt-loving". While most halophiles are classified into the Archaea domain, there are also bacterial halophiles and some eukaryota, such as the alga Dunaliella salina or fungus Wallemia ichthyophaga. Some well-known species give off a red color from carotenoid compounds, notably bacteriorhodopsin. Halophiles can be found anywhere with a concentration of salt five times greater than the salt concentration of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds.
Halophiles are categorized as slight, moderate, or extreme, by the extent of their halotolerance. Slight halophiles prefer 0.3 to 0.8 M (1.8 to 4.7% - seawater is 0.6 M or 3.5%), moderate halophiles 0.8 to 3.4 M (4.7 to 20%), and extreme halophiles
