Özet: Nitrogen is an essential nutrient for plant and animal growth. In addition, all microorganisms require nitrogen for protein synthesis andgrowth. But, nitrate contamination of current and potential drinking water sources is a serious and ever-increasing problem. The toxicity of nitratesfor humans is not clearly understood. However, their consumption can cause infant methemoglobinemia. Reduction of nitrates into nitrites maycontribute to the formation of nitrosoamines, which are known carcinogens. Therefore, various unit processes have been used for nitrate removalfrom drinking water and wastewater. Biological denitrification is highly selective for nitrate removal. Moreover, biological denitrification havebeen used for years in wastewater treatments. Heterotrophic or autotrophic microorganisms have been used in biological denitrification. Biologicaldenitrification is cheaper than the other methods. Therefore, biological denitrification has been prefered. This review is preapered for this reason.
