The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866. Subsequently, the phylum was elevated to the rank of kingdom in 1925 by Édouard Chatton. The last commonly accepted mega-classification with the taxon Monera was the five-kingdom classification system established by Robert Whittaker in 1969.


Classification of Monera. Kingdom Monera is classified into three sub-kingdoms- Archaebacteria, Eubacteria, and Cyanobacteria. Archaebacteria. These are the most ancient bacteria found in the most extreme habitats such as salty area (halophiles), hot springs (thermoacidophiles), and marshy areas (methanogens).


The Monera kingdom includes all bacteria that may infect animals, humans, and plants. But most of the members are termed as beneficial bacteria, rather than pathogenic bacteria. The Monera kill organisms causing pathogenic diseases, breaks down algae, and can even recycle chemical pollutants like hydrogen sulfide and ammonia.

Monera Definition. Monera is a kingdom in biology that comprises prokaryotes, which are single-celled organism that have no true nucleus.Monera is the most ancient group of organisms on earth, as well as the most numerous. In this kingdom, the organisms have naked DNA that forms a clump called the nucleoid, as shown below, while organisms in all other kingdoms have DNA enclosed in a nucleus.


Eubacteria were previously under the kingdom 'Monera' which also included Archaebacteria. But later, due to the differences between these two taxonomies and large number of eubacteria, they were separated and a new kingdom was created with the name Eubacteria.


Kingdom Monera, Protista And Fungi. Billions of years of evolution have led to a mind-numbing variety of species on earth. Classification of these organisms was a serious challenge for the biologists. Many researchers had come forward with different categories to classify living things. Among them, Ernst Haeckel (1894), Robert Whittaker (1959 ...


DESCRIPTION OF THE DOMAIN EUBACTERIA (EHRENBERG 1828) EUBACTERIA: Eubacteria (pronounced: u-bak-TE-ree-a) is a combination of two Greek root that mean "well or true" (eu - εὖ) and "little stick" (bakterion -βακτήριον). These organisms have many names and synonyms that are in common and technical usage.


Spirillum, genus of spiral-shaped bacteria of the family Spirillaceae, aquatic except for one species (S. minus) that causes a type of rat-bite fever in man. The term spirillum is used generally for any of the corkscrew-like species. Spirillum is microbiologically characterized as a gram-negative,
