Psychrophiles, halophiles, methanogens and thermophiles are all examples of Archaebacteria, according to the American Society for Microbiology. The University of California Museum of Paleontology defines Archaebacteria as members of the domain Archaea. Because organisms from this domain do not have the same genetic and biochemical makeup as bacteria, many scientists refer to them as Archaea instead of Archaebacteria.Know More
Psychrophiles live in areas with extremely cold temperatures, notes the American Society for Microbiology. Psychrophiles are very hardy organisms because they are able to survive when their enzyme activity is suppressed or they have decreased membrane fluidity, according to a 2006 article in Embo reports. In contrast, thermophiles are able to survive at extremely high temperatures. Experts from the Science Education Resource Center at Carleton College say optimal growing temperatures for thermophiles range from 60 to 108 degrees Celsius.
Many organisms cannot survive in overly salty conditions, but halophiles thrive in salty environments, according to the American Society for Microbiology. Methanogens are often found in wetlands and within the human digestive system. These organisms produce methane as a byproduct of some chemical processes. In humans, the methane is released in the form of flatulence or belching, explains Wikipedia. In wetlands, methanogens produce the methane that gives marsh gas its characteristic odor.Learn more about Biology
People classify things as an organizational tactic, according to The American Society for Microbiology. Classification helps people monitor items, animals, people and events. It also helps people to contrast and compare items. Scientists practice the classification of living things to enhance their understanding of relationships among living creatures.Full Answer >
Members of the archaebacteria kingdom reproduce asexually by binary fission or recombination through conjugation or fragmentation. Transference, the process by which bacterial viruses pass genetic material between hosts, may occur between archaea and its viruses.Full Answer >
The main characteristic of archaebacteria and eubacteria are that they are unicellular, or single-celled. Archaebacteria are only found in hot boiling water or other types of extreme environments, while eubacteria are found all over.Full Answer >
Some archaebacteria are photosynthetic, meaning they make their own food; however, rather than use the pigment chlorophyll like green plants and algae, they employ a light-sensitive purple protein called bacteriorhodopsin. Other archaea live in places where no sunlight penetrates, such as deep-sea thermal vents. These bacteria rely on a process called chemosynthesis to make ATP.Full Answer >
