硝化细菌

After years' effort, a new aerobic denitrifier that can deoxidize NO 3 - to N 2 and N 2 O has been isolated from ocean environment. Compound bacterial production is made up of aerobic denitrifying bacteria, nitrifying bacteria and organic compound degrading bacteria.

本项目将好氧还硝化菌、硝化细菌和有机质高效降解菌制成复合微生物制剂，通过多种微生物共同作用，在好氧的条件下能同时进行有机质降解、硝化作用和反硝化作用，可有效降低水中的三氮（ NH 4 +、 NO 2 -、 NO 3 -）。

Objective To study the community of denitrifying bacteria and nitrate-nitrogen removal in downflow fixed-bed bioreactor.

目的研究下流式固定床反应器的脱氮效果及反硝化细菌群落结构。

In conclusion, strains ZW23 and ZW27 are two typical facultative aerobic denitrifiers of high efficiency in the removal of N from water.

菌株ZW23和ZW27是两株典型的高效兼性好氧反硝化细菌，具有重要的应用价值。

Denitrifying bacteria such as Pseudomonas, Micrococcus, and Clostridium use nitrate as the terminal electron acceptor in anaerobic respiration.

反硝化细菌有假单胞菌，微球菌以及梭菌。它们在厌氧呼吸中都能使用硝酸盐作为最终电子受体。

Objective To study the best conditions of nitrification for nitrobacteria so as to provide the basis for nitrobacteria production and application.

目的探讨硝化细菌最佳工作条件，为应用和生产提供依据。

The zeolite could be effectively regenerated under the activity of nitrobacteria and the regeneration rate reached to 80% i...

在硝化细菌的作用下沸石粉能够得到有效的生物再生，试验中再生率达到了80%。

The studies also showed that the number of nitrobacteria on temporal and spatial distribution is related with temperature and nitrogen content in the sediments.

说明硝化细菌数量的时空分布与环境温度和沉积物中N的含量有关。

On the silicate plate, pure nitrobacteria were obtained.

在硅酸胶平板上分离到硝化细菌的纯培养物。

The results showed that short SRT bacteria and nitrobacteria can be cultivated separately in the reactor so that the concentration of nitrate in the circumfluence sludge is low, which is lower than 1 mg/L.

结果表明，在反应器内能实现短泥龄细菌和硝化细菌的分相培养，有效降低了回流污泥中硝态氮的质量浓度，其值小于1mgL^(-1)。

But, this kind of condition would only occurred when a great deal of nitrobacteria are added into the water.

1去氨硝化菌能将鱼类所排放的氨转成毒性较小的亚硝酸盐，而去亚硝酸硝化菌则负责将亚硝酸盐再转成毒性更小的硝酸盐，硝酸盐必须由换水的方式移除，像硝化细菌这类的细菌再作用时需要消耗水中的氧气所以也称好氧菌。
