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.Continue Reading
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, also known simply as "bacteria," can be found in every habitat on Earth. These organisms are widely varied and very adaptable, causing many illnesses in humans but also carrying out many helpful processes as well.Full Answer >
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 >
Eubacteria are single-celled organisms capable of obtaining nutrition by using organic carbon, photosynthesis and chemosynthesis. Eubacteria may be categorized based on how they obtain nutrients.Full Answer >
