| 1. | 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 |
| 2. | 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。 |
| 3. | The decrease of populations of the nitrifiers and denitrifiers was observed in urea - applied soil plots at same time . the controlled - releasing urea could not significantly stimulate the flux of n2o
对硝化细菌和反硝化细菌数量的检测观察到，在不同的条件下，两种细菌对氧化亚氮的释放贡献不一样。 |
| 4. | The nitrogen fixation in alpine meadow ecosystem is mainly accomplished by anaerobic nitrogen fixing bacteria . both ammonification and nitrification are the highest in 0 cm 10 cm soil depth
从不同植被类型土壤的表层中各生理群菌数的平均值来看，反硝化细菌的数量最高，嫌气性自生固氮菌次之，再次为氨化菌和硝化菌。 |
| 5. | The application and development prospect of several microbial preparations such as bacillus sp . , photosynthesis bacteria , nitrobacteria , denitrify bacteria , yeasts and micro - algae which were applied on aquiculture were summarized
摘要简述了芽孢杆菌、光合细菌、硝化细菌和反硝化细菌、酵母菌等几种微生态制剂在水产养殖中的应用现状及发展前景。 |
| 6. | Glucose could obviously increase the flux of n2o among the carbon sources detected . that the methane - oxidizing bacteria probably were also one of microbiological populations producing n2o was proposed , based on research work . 2 ) methane oxidation ability of green - house soil was detected
研究也表明在自然界中除了硝化(包括自养和异养型)细菌和反硝化细菌种群以外，甲烷氧化菌可能也是对氧化亚氮释放具有一定贡献的细菌类群。 |
| 7. | 1 . ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study . little difference in total counts of bacteria , actinomycetes and fungi was observed between the contaminated and the non - contaminated soil . compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil
一、甲基对硫磷长期污染对土壤微生物的生态学效应研究了有机磷农药甲基对硫磷长期污染对土壤微生物的影响，实验表明：土壤细菌、放线菌、真菌总的数量影响不大；自生固氮菌和反硝化细菌数量减少；氨化细菌、亚硝化细菌、硝化细菌的数量在污染土壤中却有所增加；与对照土壤相比，污染土壤呼吸作用下降了29 . 93 ；氨化作用和硝化作用强度得到增强。 |
| 8. | Microbial mineralization is outlined , the effects of thiobacillus , sulfate - reducing bacteria , iron - reducing bacteria , nitrifying bacteria , denitrifying bacteria , and various bacteria that play the roles during the bio - mineralization of uranium and that correlated with the cycle of geological elements were also introduced in this article
