The amounts of waste materials discharged into bodies of water around the world are rising steadily. Increases in population, the dependence of agriculture on massive amounts of fertilizers and pesticides, expansion of the food industry, and growth of other industrial processes all contribute to the volume of sewage and wastewater and to their content of undesirable substances. Most organic waste materials may be degraded by biological treatment. This treatment utilizes the functions of microorganisms to degrade the harmful substances to make them harmless to the environment. The use of microorganisms for the treatment of waste water is an economical alternative to physical treatment systems since biological treatment involves lower capital investment, lower energy requirements, a self-sustaining operation, and finally possibility for product recovery. The biological process may be achieved aerobically or anaerobically in a number of ways. The most widely used aerobic processes are activated sludge processes and their modifications for both domestic and industrial wastewaters. The

In the aerobic phase of the treatment process, a mixed microbial population degrades the complex mixture of organic compounds in liguid waste to carbonate, nitrate, ammonia, phosphate, and sulfate. Major studies on microorganisms which decompose organic sewage and offensive odorous substance are conducted on the sewage treatment by activating sludge method. In recent years, animal industries become specialized and large scale. It is well known that there exists a great abundance of livestock feedlot and poultry excreta which pollutes not only the streams and livers with toxic compounds and pathogenic microorganisms but also the air with offensive odors. Disposal of the excreta is a serious problem which has confronted in various ways but which never has been satisfactorily solved. Countermeasures therefore are strongly needed to prevent the escalation of environmental pollution caused by excreta and recover the polluted environment by them. There is an approach to purify the polluted environment utilizing microorganisms of degradation ability. But, none of the presently known bacteria can satisfy the practical requirements and also high degradation performance when used for microbial excreta degradation.
