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.Know More
Eubacteria are all prokaryotes. This means that members of this kingdom, which is as large and diverse as the plant and animal kingdoms, lack a cell nucleus and generate energy without the symbiotic relationships that define eukaryotes.
Cyanobacteria, a type of eubacteria, are among the earliest life forms to have appeared in the fossil record. Colonial stromatophores were building large mounds, called stromatolites, on Earth 3 1/2 billion years ago. These blue-green algae, as they are often called, were the first major producers of oxygen on Earth, and they remain central to maintaining the equilibrium of Earth's atmosphere. Some cyanobacteria fix nitrogen directly from the air, enriching soil and permitting plants to thrive.
Harmful eubacteria exist as parasites. Chlamydia and the spirochetes responsible for syphilis are two examples of destructive eubacteria. E. coli is arguably another harmful bacillus. This species normally resides in the gut, where it aids digestion, but it can become dangerous in certain cases. Vancomyicin-resistant E. coli is a common infection found in hospital wards.Learn more about Biology
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, known to most simply as bacteria, are found in every ecosystem on Earth. They have a vast amount of diversity; some varieties such as salmonella and E. coli are deadly to humans, while others live within the body and assist with biological processes.Full Answer >
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.Full Answer >
Some examples of organisms within the domain eubacteria are algae, E. coli and salmonella. Also known as true bacteria, these are microscopic, prokaryotic, single-celled organisms without nuclei that produce their food by photosynthesis.Full Answer >
