ktremophiles Life Under Extreme Conditions 極端微生物 微生物的多樣性表現在其生長環境，幾乎整個生物圈環境，都有微 生物存在。雖然大多數微生物只能在中溫和中性環境中生長，但有 些微生物卻能在特殊的環境中生存，例如高溫、低溫、高鹽、高鹼 、高酸、高壓、高輻射等環境。這些微生物由於適應特殊環境的結 果，形成獨特的機能、結構和遺傳基因，這類微生物稱為極端微生 物(extreme microorganisms,extremophiles)，因為具有特殊的基因類 型、生理機制及代謝產物，是一群新型且具有很大開發潛力的生物 資源

What are extremophiles? EXTREMOPHILES are organisms that require extreme environments for growth. Extremophiles are organisms that are "fond of"or "love"(- phile)environments including high temperature,pH, pressure and salt concentration,or low temperature,pH, nutrient concentration,or water availability. Extremophiles are also organisms that can tolerate extreme conditions including high levels of radiation or toxic compounds,or those living in conditions that we consider unusual Most extremophiles are microorganisms that thrive under conditions that from a human perspective are clearly extreme
What are extremophiles? • EXTREMOPHILES are organisms that require extreme environments for growth. • Extremophiles are organisms that are "fond of" or "love" (- phile) environments including high temperature, pH, pressure and salt concentration, or low temperature, pH, nutrient concentration, or water availability. • Extremophiles are also organisms that can tolerate extreme conditions including high levels of radiation or toxic compounds, or those living in conditions that we consider unusual. • Most extremophiles are microorganisms that thrive under conditions that from a human perspective are clearly extreme
Extremophiles A vast number of extremophiles belong to the Archaea.Some Archaea live near rift vents in the deep sea at temperatures well over 100.C. Others live in hot springs,or in extremely alkaline or acid waters.More recently, scientists have also found bacteria in these extreme environments.Indeed,the ratio of thermophilic bacteria to Archaea was 50 to 1 in a range of samples taken from Yellowstone Park's Obsidian Pool

Extremophiles Extremophiles are a collection of microorganisms classified according to the following four parameters: High and low temperature:thermophiles and psychrophiles High and low pH:alkaliphiles and acidophiles High salt concentration:halophiles High pressure:barophiles
