Extremophiles
ExtremophilesExtremophiles are microorganisms that thrive in environments with extreme conditions, such as high or low temperatures or pH levels, high salt concentration, or high pressure. Found in hydrothermal vents on the ocean floor, they produce the vivid colors of some hot springs. Due to extremophiles' ability to thrive in conditions detrimental to most life on Earth, some scientists theorize that they may reflect what life may be like on other planets. How are extremophiles used industrially? More... mais »
