Archaebacteria are a type of single-cell organism which are so different from other modern life-forms that they have challenged the way scientists classify life. ... Another remarkable trait of archaebacteria is their ability to survive in extreme environments, including very salty, very acidic, and very hot surroundings.

What is the special feature of archaebacteria?
Archaebacteria are able to tolerate high temperature as well as high acidity. These bacteria are chemoautotrophic which obtain energy for synthesis of food by oxi iising sulphur, leader anaerobic conditions they oxidise sulphur to sulphuric acid.
Why archaebacteria are called special bacteria?
Archaebacteria are one of the oldest living organisms (to be known) on Earth. They are classified as bacteria because many of their features resemble the bacteria when observed under a microscope. They belong to the kingdom Archaea and hence are named Archaebacteria.
Why is archaebacteria special 11?
Archaebacteria are known to be the oldest living organisms on earth. They belong to the kingdom Monera and are classified as bacteria because they resemble bacteria when observed under a microscope. Apart from this, they are completely distinct from prokaryotes.
What is the importance of archaebacteria in our environment?
Recent data suggest that the Archaea provide the major routes for ammonia oxidation in the environment. Archaea also have huge economic potential that to date has only been fully realized in the production of thermostable polymerases.
Why are archaebacteria economically important?
- Some of the halophilic archaea carry some processes which are economically very important such as biodegradation, bioremediation and environmental processes. - Some Thermophilic archaea have enzymes which have an important role in the application of methane production, metal leaching and immobilized enzyme systems.
What are archaebacteria also known as?
Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota.
What is the difference between bacteria and archaebacteria?
Difference in Cell structure
Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
What are archaebacteria short answer?
The definition of archaebacteria are primitive bacteria microorganisms that have one cell and live in environments that are severe, such as those that are extremely salty or hot. An example of archaebacteria are methanogens.
What do you mean by archaebacteria describe its characteristics with example?
archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and ...
What is the definition of archaebacteria in biology?
Definition. noun, singular: archaebacterium. Unicellular microorganisms in the domain Archaea, which is genetically distinct from bacteria and eukaryotes, and often inhabiting extreme environmental conditions.
Can archaebacteria live without oxygen?
Most bacteria and archaea don't use oxygen to produce energy, and live an oxygen-free (anaerobic) existence. Some archaea produce methane as a by-product of their energy production, and are called methanogens. ... Other types of archaea can't live without oxygen, just like you. These are called aerobes.
What evidence suggest that archaebacteria are the ancient bacteria?
The phylogenetic evidence suggests that the archaebacteria are at least as old as the other major groups. Moreover, some of the archaebacteria have a form of metabolism that seems particularly well suited to the conditions believed to have prevailed in the early history of life on the earth.
Is archaebacteria eukaryotic or prokaryotic?
The archaebacteria are a group of prokaryotes which seem as distinct from the true bacteria (eubacteria) as they are from eukaryotes.
What are the uses of archaebacteria?
Uses of Archaebacteria:
(i) Archaebacteria are employed in the production of gobar gas from dung and sewage, (ii) In ruminants, they cause fermentation of cellulose.
What is the significance of heterotrophic bacteria?
Heterotrophic bacteria derive energy from organic compounds. They help in nutrient recycling. They decompose dead and decaying plants and animal remnants and help in biodegradation. Heterotrophic bacteria are used for making curd, antibiotics, nitrogen-fixation, etc.
How are methanogens economically important?
(1) Methane gas is produced from the dung of ruminants by the methanogens. (2) Methanogens are also involved in the formation of biogas and sewage treatment.
