中文摘要：

反硝化脱硫菌（NR-SOB）是一种具有同步硝酸盐还原和硫氧化能力的功能微生物。探讨了NR-SOB的代谢特征及其影响因素,并对它在废水处理,防腐,天然气、工业废气脱硫方面的应用进行了综述。最后,还指出了今后NR-SOB在环境应用方面的研究方向。

英文摘要：

Nitrate-reducing,sulfide-oxidizing bacteria（NR-SOB）was a functional microbe which could simultaneously denitrify and desulfurize.The metabolic characteristics of NR-SOB and the influence factors were discussed.Its application in wastewater treatment,anticorrosion,desulfurization of natural gas and industrial waste gas were also summarized.Finally,the future research directions of its environment application were pointed.
