What Are Extremophiles? Extremophiles are organisms that have been discovered on earth that survive in environments that were once thought not to be able to sustain life.These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold.Different organisms have developed varying ways of adapting to these environments, but most scientists agree that it is unlikely that life on Earth originated under such extremes.ne type of extremophiles is called thermophiles. These organisms can survive at very high temperatures. In the 1960s, heat resistant bacteria were discovered in hot springs in Yellowstone National Park.

- Most known extremophiles are microbes. The domain Archaea contains renowned examples, but extremophiles are present in numerous and diverse genetic lineages of bacteria and archaeans. Furthermore, it is erroneous to use the term extremophile to encompass all archaeans, as some are mesophilic.n extremophile (from Latin extremus meaning extreme and Greek philiā (φιλία) meaning love) is an organism that thrives in physically or geochemically extreme conditions that are detrimental to most life on Earth.

protists Xenophyophores are one-celled, multinucleate creatures found at depths of 800 to 6000 meters on the ocean floor. A characteristic feature of xenophyophores is that they construct a sort of artificial exoskeleton by gluing together particles of sediment and the microscopic shells of foraminifera.

How Extremophiles Work -- but they can also illuminate some of the important differences between extremophiles and other organisms. Before we look at a few of the environments extremophiles favor, here's a list of some additional names used to classify specific types of extremophiles: 1  Acidophile: likes acidic environments (low pH). 2  Alkaliphile: likes alkaline environments (high pH).

Characteristics of Archaebacteria Archaebacteria are found in very harsh conditions such as in the volcanic vents or at the bottom of the sea. They can easily survive in such extreme environment as sea vents releasing sulfide-rich gases, hot springs, or boiling mud around volcanoes. Archaebacteria Groups.Under the kingdom Archaea, archebacteria are classified into the following phyla: Methanogens harvest energy by converting H2 and CO2 into methane gas. They are found in the intestinal tracts of humans and some animals such as cows, and in marshes.rchaebacteria are found in very harsh conditions such as in the volcanic vents or at the bottom of the sea.

Archaebacteria: Definition & Examples Archaebacteria belong to the Domain Archaea and are single-celled organisms that tend to live in extreme environments, like hot springs or in high-salt regions. In fact, these organisms boldly go where others cannot! They have been called extremophiles, which means lover of extremes. Methanogens: These archaea release methane gas, hence the name. 2  These extremophiles are found in anaerobic habitats, or places without oxygen. 3  They can be found in your intestines as well as the guts of cows.

Extremophile An extremophile (from Latin extremus meaning extreme and Greek philiā (φιλία) meaning love) is an organism that thrives in physically or geochemically extreme conditions that are detrimental to most life on Earth. In contrast, organisms that live in more moderate environments may be termed mesophiles or neutrophiles.

Mitochondria and Chloroplast Mitochondria, which are found in nearly all eukaryotes, including plants, animals, fungi, and protists, are large enough to be observed with a light microscope and were first discovered in the 1800s. For many years after their discovery, mitochondria were commonly believed to transmit hereditary information.

Archaea Archaea were initially viewed as extremophiles living in harsh environments, such as hot springs and salt lakes, but they have since been found in a broad range of habitats, including soils, oceans, marshlands and the human colon, oral cavity, and skin.rchaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle. No clear examples of archaeal pathogens or parasites are known, but they are often mutualists or commensals.

- The vast majority of extremophiles are microbes, mainly archaea and bacteria but also some eukaryotes. These microbes live under chemical and physical extremes that are usually lethal to cellular molecules, yet they manage to survive and even thrive.Extremophiles have important practical uses.They are a valuable source of industrially important enzymes and recent research has revealed novel mechanisms and biomolecular structures with a broad range of potential applications in biotechnology, biomining and bioremediation.xtremophiles have important practical uses.

DNA in pro-/eukaryotes In eukaryotic cells, like in the maize cell shown here, DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. 2  It is present in this compartment in the form of linear chromosomes that together constitute the genome. 3  These chromosomes are identical and equal in number in all cells of an individual (except reproduction cells and mutated cells).

Extremophile An organism that does not require oxygen for growth such as Spinoloricus Cinzia. Two sub-types exist: facultative anaerobe and obligate anaerobe. A facultative anaerobe can tolerate anaerobic and aerobic conditions; however, an obligate anaerobe would die in presence of even trace levels of oxygen.ew sub-types of-philes are identified frequently and the sub-category list for extremophiles is always growing. For example, microbial life lives in the liquid asphalt lake, Pitch Lake. Research indicates that extremophiles inhabit the asphalt lake in populations ranging between 10 6 to 10 7 cells/gram.
