Classification of Bacteria on the basis of Nutrition

Nutrition is substances used in biosynthesis and energy production and therefore are required for all living things. Bacteria, like all living cells, require energy and nutrients to build proteins and structural membranes and drive biochemical processes. Bacteria require sources of carbon, nitrogen, phosphorous, iron and a large number of other molecules. Carbon, nitrogen, and water are used in the highest quantities. The nutritional requirements for bacteria can be grouped according to the carbon source and the energy source. Some types … Read more

Classification of Bacteria on the Basis of Shape

Bacteria are classified and identified to distinguish one organism from another and to group similar organisms by criteria of interest to microbiologists or other scientists. The classification of bacteria serves a variety of different functions. Because of this variety, bacteria may be grouped using many different typing schemes. The grounds for the classification commonly used may be: Morphologic Characteristics Both wet-mounted and properly stained bacterial cell suspensions can yield a great deal of information. These simple tests can indicate the Gram reaction of … Read more
