How is eubacteria different from archaebacteria

They have various characteristics. They are generally found in ocean depths. They are capable of surviving in extreme environmental conditions.

Archaebacteria are considered to be the modern form of some of the oldest bacteria found on earth. They are found in different areas around the world. They live in soil, water, and even inside and on some other organisms. All bacteria except the archaebacteria comes under eubacteria. Since they are prokaryotic, they lack a membrane-bound nucleus.

Their cell wall is generally made up of peptidoglycans in a cross-linked chain pattern. This type of structure helps them to maintain their shapes and sizes. Eubacteria have a wide range of characteristics like some bacteria have a flagellum, which is a structure made of proteins and is often used for movements. Some bacteria have pili that are small projects found on their bodies which helps them to stick on a surface or to transfer DNA. Some bacteria are even capable of forming a biofilm, which is a structure that has high antimicrobial resistance.

At certain unfavorable environmental conditions, eubacteria are capable of surviving by producing spores. It keeps them dominant over extreme conditions like high and low temperature or acidic, basic conditions, etc. Eubacteria can reproduce through binary fission and budding. Eubacteria are usually classified into three different types, i.

Mostly inhabit in extreme environmental conditions. Cell wall. Peptidoglycan with muramic acid. Variety of types, no muramic acid. Membrane lipids. Ester linked, straight -chained fatty acids are present containing L-glycerol phosphate.

Ether linked branched aliphatic chains are present containing D-glycerol phosphate. Simple subunit pattern. Complex subunit pattern similar to eukaryotic enzyme. Introns are absent. Archaebacteria: Archaebacteria are called ancient bacteria. Eubacteria: Eubacteria are called true bacteria. Archaebacteria: Individual archaebacterium is 0. Eubacteria: Individual eubacterium is 0. Archaebacteria: Archaebacteria are spheres, rods, plates, spiral, flat or square-shaped.

Eubacteria: Eubacteria are cocci, bacilli, vibrio, rods, filaments or spirochetes in shape. Archaebacteria: Archaebacteria are simple in their organization. Eubacteria: Eubacteria are more complex than archaebacteria. Archaebacteria: Archaebacteria are found in extreme environments. Eubacteria: Eubacteria are found everywhere on earth. Archaebacteria: Cell wall is composed of pseudo peptidoglycans. Eubacteria: Cell wall is composed of peptidoglycans with muramic acid.

Archaebacteria: Membrane lipids of archaebacteria is ether-linked, branched, aliphatic chains, containing D-glycerol phosphate. Eubacteria: Membrane lipids of eubacteria are ester-linked, straight chains of fatty acids, containing L-glycerol phosphates.

Archaebacteria: RNA polymerase of archaebacteria consists of a complex subunit pattern, which is similar to eukaryotic RNA polymerase. Eubacteria: RNA polymerase of eubacteria consists of a simple subunit pattern. Archaebacteria: Introns are present in archaebacteria. Eubacteria: Introns are absent in eubacteria. Archaebacteria: Asexual reproduction methods like binary fission, budding and fragmentation are used by archaebacteria during their reproduction.

Eubacteria: Other than binary fission, budding and fragmentation, eubacteria are capable of producing spores in order to remain dormant during unfavorable conditions. Archaebacteria: Archaebacteria are three types: methanogens, halophiles and thermophiles. Eubacteria: Eubacteria are two types: gram positive and gram negative. Archaebacteria: Halobacterium, Lokiarchaeum, Thermoproteus, Pyrobaculum, Thermoplasma and Ferroplasma are the examples of archaebacteria. Eubacteria: Mycobacteria, Bacillus, Sporohalobacter, Clostridium and Anaerobacter are the examples of eubacteria.

Archaebacteria, eubacteria and cyanobacteria are the three domains of kingdom monera. Archaebacteria are called ancient bacteria whereas the eubacteria are called true bacteria. Eubacteria are usually found in soil, water, living in and on of large organisms.
