Seaweed extract-EClean was applied to treatment for eutrophication water. Quantative detection of nitrogen cycle bacteria showed that seaweed extract could improve the growth of ammonifying bacteria, nitrosobacteria and nitrobacteria in the treated water. There was also an increasing trend in the number of denitrifying bacteria in aerated treatment water, which showed that the seaweed extract could accelerate nitrogen cycle and the release of nitrogen from water.

利用国外引进的海藻提取物EClean制剂对富营养化水体进行处理试验，经过定量测定处理和对照水体中氮循环细菌数量的变化，得出EClean制剂能够促进水体的氨化细菌、亚硝化细菌、硝化细菌的生长，并维持了曝气条件下一定数量的反硝化细菌，通过此处理使得在同一反应器中、同一条件下完成硝化作用和反硝化作用成为可能，加速了水体的氮素循环，使水体总氮下降明显。

The content of total Phosphorus was very high, with the average of 2.63mg/g, while the nitrite was very low and there was no relative chemic counterbalance among nitrate, nitrite and ammoniate, because the inorganic nitrogen circle was also affected by organic nitrogen in water and sediments.

以滇池马村湾和海东湾为研究对象，对其沉积物－间隙水－上覆水三界面中的磷、氮形态作研究，其中钙结合态磷占的比例最大，其次是有机/细菌聚合态磷和残渣磷；总氮含量很高，平均值为2.63 mg/g，而亚硝酸盐氮含量很低，其它三种无机氮形态（硝酸盐氮、亚硝酸盐氮和氨氮）之间并不存在恒定的化学计量关系，这主要是无机氮循环还受水体和沉积物中有机氮的影响。

The results of culture experiment show that the volume of the gas produced by ammonification in the vagetated water is about 2 times as much as that in the unvegetated open water.

各种水生高等植物群落内氮循环细菌分布及微环境的差异，促进了有机氮的分解、铵态氮的硝化和挥发、硝酸盐氮的反硝化作用。

Nitrogen mineralization is one of the most important aspects in soil nitrogen circulation.

氮的矿化是土壤氮循环中的重要环节之一。

Nitrification is one of the most important step is the nitrogen cycle, this series of reactions are responsible for chemoautotrophic nitrobacteria, therefore the chemoautotrophic nitrobacteria play an important role in nitrogen cycle.

摘要 硝化作用为整个氮循环的必须步骤之一，这一连串的反应主要由自营性的硝化菌负责，因此，自营性硝化菌在氮循环中扮演著关键的角色。

The atmospheric phase is predominant in the global nitrogen cycle, in which nitrogen fixation and denitrification by miocroorganisms are of particular importance.

在全球氮循环中，气相是占优势的，其中，氮的固定和微生物的脱氮作用特别重要。

The atmospheric phaseis predominant in the global nitrogen cycle, in which nitrogen fixation and denitrification by miocroorganisms are of particular importance.

The broader issue, therefore, is the extent to which humanity has hijacked the "nitrogen cycle", as the passage of that gas into and out of the atmosphere is known, for its own use.

因此更为广泛的问题是人类"劫持""氮循环"的程度，氮循环是氮气自身使用过程中进出大气的过程。

In nitrogen-fixing populations this 'new' nitrate and nitrite can be derived from the assimilation of nitrogen gas.

这些自己"堆肥"的豆科植物还能在其根瘤中的共生细菌的帮助下固定大气中的氮，从而将氮循环的主要步骤综合在一种生物中。

Genetic diversity of carbon-nitrogen cycle was relative to soil organic matters,total nitrogen,carbon-nitrogen ratio,available phosphor and water content with different degrees.

碳氮循环基因多样性与土壤有机质、全氮、碳氮比、速效磷和土壤含水量等生态因子有不同程度的相关。
