What is an Acidophile in biology?
Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions (usually at pH 5.0 or below). These organisms can be found in different branches of the tree of life, including Archaea, Bacteria, and Eukarya.
What is the difference between Halophiles and thermophiles quizlet?
What is the difference between halophiles and thermophiles? Halophiles require high salt concentrations (greater than 9%) and thermophiles require high temperatures (greater than 45°C) for optimal growth.
What domain is Acidophile?
Natural niches where acidophiles can be found are volcanic areas (Yellowstone), hydrothermal sources, deep-sea vents, metal mining activities (Iron Mountain, Río Tinto) or in the stomachs of animals. Acidophilic organisms can be found in the different domains of the tree of life ( Archaea, Bacteria, and Eukarya).
Which bacteria is considered an Acidophile?
Some of the organisms considered as acidophiles are as follows:
- Archaeal Richmond Mine acidophilic nanoorganisms, i.e. archaea living in extremely acidic mine in Richmond Mine at Iron Mountain in northern California.
- Acetobacter aceti, i.e. a bacterium capable of producing acetic acid through oxidizing ethanol.

Is E coli an Acidophile?
Surprisingly, certain microorganisms that grow at neutral pH have elegantly regulated systems that enable survival during excursions into acidic environments. The best-characterized acid-resistance system is found in E. coli.
What is the difference between Halophiles and thermophiles?
Halophiles are bacteria that thrive in high salt concentrations such as those found in salt lakes or pools of sea water. Thermophiles are the heat-loving bacteria found near hydrothermal vents and hot springs.
What are Psychrophiles Mesophiles and thermophiles?
Psychrophiles grow best in the temperature range of 0–15 °C whereas psychrotrophs thrive between 4°C and 25 °C. Mesophiles grow best at moderate temperatures in the range of 20 °C to about 45 °C. Pathogens are usually mesophiles. Thermophiles and hyperthemophiles are adapted to life at temperatures above 50 °C.
What is Acidophile in microbiology?
Microorganisms living in permanently acidic environments are known as ‘acidophiles’. Some are extreme acidophiles typically growing at pH <3, and others are moderate acidophiles with an optimal growth in the range of pH 3–5.
Which is the example of acidophilic organisms?
In which environment are you most likely to encounter an Acidophile?
Acidophiles include certain types of eukaryotes, bacteria and archaea that are found in a variety of acidic environments, including sulfuric pools and geysers, areas polluted by acid mine drainage, and even our own stomachs.

How is a Acidophile adapted to its environment?
2.4. Acidophiles thrive under highly acidic conditions such as marine volcanic vents, and acidic sulfur springs, acid rock drainage (ARD) and acid mine drainage. These microorganisms have adapted themselves by maintaining their cellular pH neutral and also acquire resistance towards metals [24,63,64].
