| 摘 要： | 在厌氧污泥中分离得到一株自养厌氧反硝化细菌,它可以利用还原铁粉脱去污水中的硝氮,同时,废水中的磷也同时得到了脱除。大量试验发现,整个生物反应过程中没有NO2-和NH4+的积累,说明反硝化的产物是N2。通过对该菌株的16S rDNA序列同源性比较以及鉴定,在Genbank中BLAST后,初步判定它为假单胞菌属,该菌种与Pseudomonas sp.HPC502的同源性达到了99%。

| Abstract: | An autotrophic bacterium has been isolated from anaerobic sludge, which is able to reduce nitrate in wastewater producing nitrogen by using iron as the electron donor. The study of its 16S rDNA sequence, as is compared with the published data in the GenBank indicates that the BLAST level of similarity to Pseudomonas sp. HPC502 is as high as 99%. |
