硝化菌属

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 characters and performance of the biofilm were studied. When the concentration of nitrite is 206.82 mg/L, the velocity of nitrification is 260 mg/L·d. The best performed bacteria, N-20, were identified as Nitrobacter sp.

实验得到了稳定的自养硝化生物膜；当NO-2浓度为206.82mg/L时，生物膜的稳定硝化速率可达260mg/L·d；经鉴定，硝化速率最高的N20菌株属硝化杆菌属(Nitrobactersp。)。

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。

The results indicate that (1) After acclimation and induction, Phosphorus Accumulating Organism not only has the characteristics of denitrification, but also has the characteristics of takeup phosphate in aerobic;(2) Denitrifying phosphate accumulating bacteria using NO3- as electron acceptor indeed existed in the conventional enhanced biological phosphorus removal system;(3) The facultative anaerobe seperated during the process of acclimation are Corynebacterium, Pseudodiphtheria corynebacterium, Staphylococcus and Moraxella; all of which can be functioned as denitrifying phosphorus accumulating to various degree.

试验结果表明：(1)好氧聚磷菌经驯化诱导后不但具有反硝化产氮特性，而且具有好氧聚磷特性；(2)在传统的A2O 工艺中存在有以NO3-为电子受体的反硝化聚磷菌；(3)在驯化过程中分离到的兼性厌氧微生物有棒状杆菌属、假白喉棒杆菌、葡萄球菌属及莫拉氏菌属，且都有不同程度的反硝化聚磷功能。

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。
