| 1. | The nitrifying bacteria are chemosynthetic autotrophs . 硝化细菌是化能合成的自养生物。 |
| 2. | The autotrophic nitrifying bacteria play a critical role in nitrogen cycle in nature 硝化细菌是一大类在自然界氮循环中起关键作用微生物菌群。 |
| 3. | Of these , we can identify anoxygenic phototrophs , sulphate reducers and methanogens 从这些里面,我们可以辨认出无氧光合自营菌,硫酸盐还原菌,以及硝化细菌 |
| 4. | Study on nitrate - nitrogen removal and community analysis of denitrifying bacteria in downflow fixed - bed bioreactor 下流式固定床反应器中反硝化细菌类群及其脱氮效率分析 |
| 5. | Provides the aquarium and essential bacteria with all the trace elements , minerals needed for strong immune systems 全面补充宠鱼、硝化细菌所需营养,提高宠鱼防病能力。 |
| 6. | It was showed that temperature and quality of inlet water would affect the activity of denitrification 受进水水质和低温天气的影响,反硝化细菌制剂的净化作用及反硝化作用不能充分发挥。 |
| 7. | Greatly increases the available surface area for the essential bacteria to live in . this greatly increases the level of biological filtration 增大硝化细菌居住空间,促进硝化细菌繁殖,使生物过滤能力倍增。 |
| 8. | The phylogenetic analysis of strain hn was performed by phylips and the phylogenetic tree of strain hn and the neighbouring nitrifiers was given 并用phylips程序将该菌株与报道的相关硝化细菌进行系统发育进化分析。 |
| 9. | A rapid enumeration method for nitrifying bacteria was developed using the 2 - ( p - indophenyl ) - 3 - ( p - nitrophenyl ) - 5 - phenyltetrazolium chloride ( int ) ? dehydrogenase assay 荧光原位杂交( fish )可快速检测硝化细菌的数量和分布情况。 |
| 10. | The detection and application of nitrifying bacteria is limited by their peculiar ecophysiology such as strict autotrophic bacteria and slow growth 由于它们严格自养、生长缓慢的生态生理属性,使硝化细菌的检测和应用等受到限制。 |
