With the increase in industrial and agricultural activities, a large amount of nitrogenous compounds are released into the environment, leading to nitrate pollution. The perilous effects of nitrate present in the environment pose a major threat to human and animal health. Bioremediation provides a cost-effective and environmental friendly method to deal with this problem. The process of aerobic denitrification can reduce nitrate compounds to harmless dinitrogen gas. This review provides a brief view of the exhaustive role played by aerobic denitrifiers for tackling nitrate pollution under different ecological niches and their dependency on various environmental parameters. It also provides an understanding of the enzymes involved in aerobic denitrification. The role of aerobic denitrification to solve the issues faced by the conventional method (aerobic nitrification-anaerobic denitrification) in treating nitrogen-polluted wastewaters is elaborated.
随着工农业活动的增加，大量含氮化合物被释放到环境中，导致硝酸盐污染。环境中存在的硝酸盐的危险影响对人类和动物的健康构成了重大威胁。生物修复为解决这个问题提供了一种具有成本效益和环保的方法。好氧反硝化过程可以将硝酸盐化合物还原为无害的氮气。本文综述了好氧反硝化菌在不同生态位处理硝酸盐污染中的作用及其对各种环境参数的依赖性，并对参与好氧反硝化的酶进行了简要介绍。阐述了好氧反硝化在解决传统方法（好氧硝化-厌氧反硝化）处理含氮废水所面临的问题方面的作用。
