Like almost all bacteria, the bacteria of teh Eubacteria Kingdom can be found almost anywhere, but they are most common in moist areas. These bacteria like those of the Archaebacteria Kingdom are unicellular, and prokaryotic. They are the oldest kind of organisms to live on the earth. They lack a membrane bound nucleus as well as organlles, but they do have a cell wall althought it is chemically different than the plants cell walls. Most of these organisms in this group are hetertrophs. They have a huge role in nitrogen fixation, which is where they convert nitrogen into forms that can be used by plants. A special kind of bacteria are called Cyanobacteria. They are photosynthetic and light absorbing pigments in their plasma membrane which makes them appear green.

3 Phylum's of this Kingdom

The first main Phylum of the Kingdom is Cyanobacteria. The Cyanobacteria perform plant like photosynthesis and they release oxygen as a by product. They produce oxygen and food for other organsims, as well as playing a huge role in the ecosystem. All this makes them much larger than a lot of prokaryotes. These bacteria lack a membrane bound nucleus as well as chlorplasts. They can be many different colors such as yellow, red, brown, green, and even black. They are usually encased in jelly like substances, and they form colonies by clinging to one another. They are the onlt Eubacteria that does this. A second phylum is the Spirochetes. These are spiral shaped heterotrophic bacteria. Some of them are anaerobic, and others are aerobic. They move in a corkscrew like rotation, and they live freely either symbiotically or parasitically. They are Gram negative bacteria which means that they have an extra lipid layer on the outside of the cell wall, and they usually appear pink. This extra lipid layer stops many antibiotics from entering the bacteria therefore making it more difficult to kill. The third phylum is Proteobacteria. This is the largest and most diverse phylum in this kingdom. These bacteria are nitrogen-fixing. They convert inorganic nitrogen into forms in which the plants can use. One of the many subdivisons in this phylum is the chemoheterotrophic which are proteobacteria that are parasitic. Many of them are harmless and are able to participate in either aerobic or anaerobic respiration. Another subdivsion is the chemoautotrophic proteobacteria. These bacteria are free living species that paly a part in the chemical cycles in the enviornment, such as nitrogen fixation.

Escherichia coli

Escherichia coli more commonly known as E.coli is a bacteria that for the most part is good. In fact this kind of bacteria along with other kinds within our intestines is necessary for us to operate and develop properly, and to remain healthy. This type of bacteria is usually found in the intestines of healthy humans, and healthy animals. However this bacteria can also be bad for you. It can cause severe bloody diarrhea and abdominal cramps. In certain people like children under five, and the elderly people it could cause a complication called hemolytic uremic syndrome, which can result in your kidney's failing. There is antibiotics for this infection if you were to get it, and most people are fine after 5-10 days. The disease can be spread by close contact or by food. E.coli can survive refrigeration and freezer storage. To get rid of the bacterica cooking throughly at 160 degrees F is probably the best way.
