反硝化的

Firstly,the paper introduces methods if denitrification determination, as well as its advantages and disadvantages.

概述不同检测反硝化速率的方法，并对比各种方法的优点与缺点。

Not only has denitrification consumed substantial nitrate, but decomposed a certain mass of organic matter.

反硝化作用不仅消耗大量的，而且还造成了一定量的有机质降解。

ABSTRACT Bacillus halodenitrificans (ATCC 49067), a moderate halophile, facultative anaerobe and Gram-positive denitrifier, reduces both nitrate and nitrite to nitrous oxide as the final denitrification product.

Bacillus halodenitrificans（ATCC49607），是一种能将硝酸根和亚硝酸根还原成终产物N〓O的中性嗜盐、兼性厌氧的格兰氏阳性反硝化真细菌。

NO -x in the leachate effluent was still above 50 mg/L , which was mainly contribut2

在持续有氧的区域，阻碍了对其的完全反硝化。

In the range of the C/N ratio of 1～14, nitrate reduction mainly occurred in the growth phase of the 4～10 hour and there was minim nitrite accumulation in the process.

当C/N在1～14之间变化时，硝酸盐还原基本都发生在菌株生长的第4～10h，整个反硝化过程中亚硝酸盐浓度一直保持在极低的水平。

Our study was the first report comparing the microbial structure of two effective denitrifying communities which could efficiently degrade quinoline and indole.

首次报道并比较了可高效降解喹啉和吲哚的反硝化生物反应器的微生物群落结构。

Reducing ammonic volatilization and nitrification,using high N use efficiency and low N responsiveness simultaneously are the main approaches of sustainable development in agriculture to improve utilization ratio of nitogen,decrease environmental pollution and waste of resources.

减少氨的挥发和反硝化作用，选育氮高效、耐低氮品种是提高氮素利用率、减少环境污染与资源浪费和实现农业可持续发展的主要途径。

The development of modern molecular approaches independent of culture enables the accurate and comprehensive study of denitrify .

现代非培养分子技术的发展使得对反硝化微生物进行原位，准确，全面的研究成为可能。

By controlling the nitrate concentration in the anoxic stage,the methods and effects of inducing Denitrifying Phosphate Accumulating Organisms were studied.

通过控制缺氧段硝酸盐浓度，研究了反硝化聚磷菌的诱导方法及效果。

Denitrification is a microbial process in which oxidized nitrogen compounds are used as alternative electron acceptors for energy production.

反硝化是微生物以氮氧化物作为电子受体产生能量的过程。
