Some bacteria degrade organic compounds for energy, and without bacteria, the earth would have no soil in which to grow plants. Bacteria living in the gut can help animals break down food. These So-called ‘ good bacteria’ help to maintain the condition necessary for food digestion. some bacteria live on the root nodules of certain plants, for example, peas, beans and clover, and are able to ‘fix’atmospheric nitrogen into a form that can be absorbed by the plant as a fertiliser. We are also able to use bacteria to break down our sewage and to clean up oil spills. We can manipulate bacteria to grow a protein of interest, for example, insulin, and then grow them in large vats to produce a large quantity of the desired protein. Bacteria play an important role in the development of healthy food production, environmental protection, and ecological balance as well as the use of Micro-organisms for the management of crops of pest in the future will play an important role in the field. If farmers use these Micro-organisms as an alternative to lethal chemicals, then grain production will be able to support the development of organic farming.
