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.Know More
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.Learn more about Biology
Eubacteria and archaebacteria have a wide variety of shapes. However, these cell types have no membrane-bound organelles, they do not organize their DNA into a nucleus, and they are contained by cell membranes protected by cell walls. Both are relatively simple in structure, so most of their differences are chemical, not structural. In general, archaebacteria have commonalities with eukaryotes that eubacteria lack, but they also have some truly unique features.Full Answer >
There are four modes of nutrition for the kingdom Eubacteria: photoautotrophs, chemoautotrophs, photoheterotrophs and chemoheterotrophs. Each of these has a different combination of ways that they obtain energy and carbon.Full Answer >
Eubacteria is a huge, diverse kingdom of prokaryotic microbes that includes chlamydia, E. coli and cyanobacteria. Eubacterial organisms are used to make cheese and wine. They can cause serious infections in humans and sometimes, as in the case of human gut flora, they change quickly from helpful to harmful.Full Answer >
Eubacteria are one of the two major groups of single cell organisms that lack nuclei and many other organelles found in eukaryotes. They have vast diversity, with a wide range of habitats and lifestyles, but all either have an elongated helical shape, a rod shape or a sphere shape.Full Answer >
