The strain could denitrify sodium nitrate in aerobic environment and nitrify in the culture media with sodium acetate as carbon source and ammonium sulfate as nitrogen source , as well as acetamide as the sole carbon and nitrogen sources .

该菌株以硝酸钠为氮源时能进行好氧反硝化作用；以乙酸钠和硫酸铵分别为碳源和氮源能进行异养硝化作用，能以乙酰胺为唯一碳源和氮源进行生长。

Exploratory study was made on the Guanting reservoir influent treatment by using two-stage BAF at extreme low temperature.The results show that the removal of organics and ammonia nitrogen is seriously inhibited due to low temperature,and the conversion of nitrite into nitrate is no longer a limiting factor of complete nitrification.One possible hypothesis is that the activity of nitrobacter is hi gher than that of nitrosomonas at extreme low temperature.

摘 要：两级曝气生物滤池在极低温度下(1℃以下)处理官厅水库入库水的探索性研究试验结果表明，有机物和氨氮的去除受到了低温的严重抑制，亚硝酸盐转化成硝酸盐不再是完全硝化反应的限制步骤，这可能是在极低温度条件下硝酸菌的活性高于亚硝酸菌活性的缘故。

Results of P-uptake experiments show that 11 isolates have denitrifying and P-uptake ability, and JB2 and JB3 identified as Pseudomonas and Alcaligenes have the best P-uptake ability. After 8 h, 13.76 mg/L and 11.85 mg/L PO(superscript 3- subscript 4)-P can be removed.

结果表明有11株菌均具有不同程度反硝化吸磷能力，其中假单胞菌属的JB2和产碱菌属的JB3脱氮除磷效果最好，8h后磷的去除量分别为13.76mg/L和11.85mg/L。

The streptomyces was found for the first time to be able to oxidize ammonia to nitrite. The denitrifying bacteria were found for the first time to be able to oxidize ammonia anaerobically. The ANAMMOX bacteria were isolated for the first time in pure culture and a new method for ANAMMOX bacteria isolation was developed.

首次发现链霉菌具有亚硝化能力，首次发现反硝化细菌具有ANAMMOX能力，首次获得具有ANAMMOX活性的腐霉状菌纯培养物，并建立ANAMMOX菌的分离方法。

Strain H1 could denitrify under shallow shaking conditions as well as in the initial atmospheric oxygen concentration ranging from 0~21%.

在150 mL的培养液中，连续以2 L/min的速率通气， H1依然能够反硝化，但是更高的通气速率则反硝化停止。16S rDNA序列分析表明，菌株H1与Ralstonia taiwanensis相似性达98%。

Stable nitritation is realized because the nitrobacter is sensitive to the changing environment. When the dissolved oxygen and pH values in SBRⅠ and SBRⅡ are 2. 4-3. 0mg/L, 7. 0-8. 5, 1. 5-2. 0mg/L and 7. 0-8. 5 respectively, a lot of nitrate isn't found during operation in two months, and nitrosation rate is over 80% in two aerobic reactors.

将SBRⅠ、SBRⅡ好氧反应器的溶解氧、pH分别控制在7.0-8.5、2.4-3.0mg／L及7.0-8.5、1.5-2.0mg／L时，依赖SBR反应器水质波动大、硝酸菌对环境变化敏感的特点，在较高浓度NH〓-N条件下，实现了稳定的亚硝化反应，系统运行近两个月，没有大量硝酸盐的积累，两个好氧反应器的亚硝化率均在80％以上。

Nitrobacter can gradually acclimate to nitrous nitrifying conditions and refreshed, so the sludge should acclimation and the nitrite accumulation disappear.

3低浓度氨氮废水亚硝化系统稳定运行一段时间之后，硝酸菌能逐渐适应亚硝化条件，恢复活性，从而使污泥产生适应性，亚硝化现象消失。

Result The identification showed that the strain ZW38 belonged to Nitrosomonas and ZL5 belonged to Paracoccus.

结果］经鉴定，菌株ZW38属于亚硝化单胞菌属，菌株ZL5属于副球菌属。

In this study, denitrifying phosphorus accumulating bacteria was cultivated in an sequencing batch reactor.

本试验研究在间歇式反应器中，以NO3-为电子受体的反硝化聚磷菌的生理生化特性、好氧吸磷功能，同时对其反硝化聚磷性能进行了考察。

Denitrification gradually took over methanogenesis to become the main reaction responsible for decomposition of MSW, while nitrogen gas was generated instead. Additionally, owing to long term exposure of nitrified leachate to MSW, the bacterial structure of landfill was changed.

在此过程中，反硝化逐渐代替产甲烷作用成为填埋场内垃圾降解的主要反应，产生气体以氮气为主，而非甲烷；硝化渗滤液与垃圾的长期作用也改变了填埋场的菌群结构。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
