氨化细菌

The results showed that methamidophos inhibited the growth and activity of bacteria, Actinomyces and Azotobacter at different degree, but stimulated the growth of fungi; the results also showed that soil respiration and ammonification was stimulated, however, soil nitrogen fixation, nitrification and Fe－reduction was inhibited.

结果表明，甲胺磷对细菌、放线菌和固氮菌群的生长具有不同程度的抑制作用，而对真菌却有一定的刺激效应；土壤的呼吸作用、氨化作用增强，自生固氮能力、硝化作用以及铁离子价数转换作用减弱。

The number of bacteria、fungi、ammonifier、cellulose-decomposing bacteria and the activity of urease、cellulosase、proteinase and phosphatase in organic and inorganic mixed substrates were significantly higher than that in inorganic mixed substrates.

The results showed that the ammonifying rate, nitrifying rate, nitrosifying rate and denitrifying rate of bacteria in pond silt were significantly affected by the biomass and population composition of bacteria, physio-chmical characteristics of pond silt and water quality.

结果表明：淤泥中细菌的氨化率、亚硝化率、硝化率和反硝化率在很大程度上受淤泥中有机物的含量、细菌数量和种群组成、淤泥的理化性质及水质情况的影响。

Five different selective culture medium were used for sewage microorganisms directional isolated cultivate, advantage compound bacteria of photosynthetic bacteria, ammonifying bacteria, nitrifying bacteria, denitrifying bacteria and phosphate solubilizing bacteria could be gained through enrichment cultivate, then compounded them and used in test wastewater static treatment.

采用5种选择性培养基对水样中的微生物进行定向分离，通过富集培养，可以得到光合细菌、氨化菌、硝化菌、反硝化菌和磷细菌的优势菌群，进行复合后，再对试验污水进行静态处理。
