The Controlof Bacteria

The control of bacteria Introduction Aim: To determine which germicide kills or precludes bacterial ontogenesis the best. Controlling microbial return is important and needful for human health (spoilage of food) and the environment. Many microbes in addition have a positive effect on the environment by degrading sewage and harmful chemicals. bacterium be single celled organisms. Disinfectants and antiseptics take aim the cell fence and a plasma membrane. By damage the cell wall it prevents cell lysis. The plasma membrane is quiet of a phospholipid bilayer and by destroying it the cell loses its selective permeability. This is so to inhibit microbial growth. Controling microbial growth can be do in cardinal ways by inhibiting the growth or by cleansing the growth and is done by personal or chemical agents. Bactericidal agents kill the bacterial cells and bacteriostatic agents inhibit or prevent the growth of bacteria. For example a fungicide kills fungi. A lot of bacteriostatic agents are also bactericidal.
