What are eubacteria?


Eubacteria are considered to be "true bacteria," according to Reference.com. They are characterized by a lack of nuclear membrane, single circular chromosome and have cell walls composed of peptidogycan.

A popular classification system divides all living beings into three domains: eubacteria, archaea and eukaryotes. The word "eubacteria" derives from the words "eu," which means "true" and "bacteria." Eubacteria are prokaryotes, which mean they have a primitive nucleus. The nuclear material of bacteria is not bound by a distinct nuclear membrane, as in eukaryotes. Also, bacterial genetic material, or the DNA, is present as a single circular chromosome.

The cell wall of bacteria is composed of peptidoglycan, as opposed to cellulose, like in plants. They are single celled organisms, and mostly reproduce through binary fission. Eubacteria are either motile, or non-motile. The motile bacterium are able to move, due to the presence of a flagellum.

Eubacteria can form spores, which allows them to survive for a long time in adverse conditions, notes the Augusta Technical College. Eubacteria are further classified as either gram positive bacteria, or gram negative bacteria, depending on whether or not they take in a gram stain. Eubacteria and Archaebacteria evolved from a common ancestor, but have enough differences to merit two separate domains in the classification of living beings.
