The Archaea is similar to the bacteria in terms of cell structure and size, although possess many distinctive features, including the lack of peptidoglycan in their cell wall, existence of exclusive membrane lipids that are not established in the other domains of life and other distinctive genetic and biochemical properties. Most cultured Archaea were actually recovered from tremendous environments where there are high temperatures, high salt concentration and acidic hot springs. The exclusive properties of the Archaea can be subjugated in biotechnology. In addition culture independent studies illustrate that Archaea are also extensive in non tremendous environments such as soil and sea water (Kates, Kushner, & Matheson, 1993). Bacteria are normally clustered in a number of diverse ways. Most bacteria are of one of three archetypal shapes: round shaped, spiral shaped and rod shaped. An additional group Vibrios comes out as partial spirals. In most bacterial cells the plasma membrane and the cytoplasm are bounded by a cell wall. Extra categorization of bacteria is based on cell wall distinctiveness. Some bacteria which are known as aerobic forms can function metabolically only in the existence of atmospheric oxygen while others which are known as anaerobic bacteria cannot grow in presence of free oxygen but acquires it from compounds (Zannoni, 2004). In terms of modes of nutrition bacteria and Archaea are clustered into two types: the Autotrophic and Heterotrophic. The Autotrophic do not necessitate organic food since the organism is capable of living on inorganic molecules down with some sort of energy source. An example of archaea is Methanogens whine an example of the bacteria is E. coli or Strep (Zannoni, 2004). Since Archaea lack cell nuclei they do not produce through mitosis: moderately, they
