After years' effort, a new aerobic denitrifier that can deoxidize NO 3 - to N 2 and N 2 O has been isolated from ocean environment. Compound bacterial production is made up of aerobic denitrifying bacteria, nitrifying bacteria and organic compound degrading bacteria.

本项目将好氧还硝化菌、硝化细菌和有机质高效降解菌制成复合微生物制剂，通过多种微生物共同作用，在好氧的条件下能同时进行有机质降解、硝化作用和反硝化作用，可有效降低水中的三氮（ NH 4 +、 NO 2 -、 NO 3 -）。

In which the microorganism fouling was the main reason why the RO system operated and run diffidently, such as a great deal of sticky biofilm were attached to the surface of RO membrane, and which led to a higher influent press, a lot of energy consumption and lower water production and so on.

分析认为，RO膜污染主要来自无机物、胶体、有机物和微生物污染，其中微生物污染是造成反渗透水处理运行困难的重要原因，它会造成反渗透膜表面出现大量粘泥状生物膜，使进水水压过高，增大能耗，或造成膜的产水量下降。

Soil microbial biomass and activities of invertase and urease all tended to decrease after pot-culture experiment, while the correlations between these biochemical properties and field ages were similar to those before this experiment, suggesting that rice cultivation without fertilization consumed part of soil microbial biomass, decreased soil enzyme activities correlated with C and N transformation, and affected soil nutrients status disadvantageously.

温室盆栽试验之后，水稻土的微生物生物量及酶活性与利用年限之间的关系规律和种植水稻之前基本一致，且整体上又趋于下降，即无施肥条件下种植水稻转化利用了土壤部分微生物生物量，并减弱了与碳氮转化相关酶的活性，对保持水稻土的营养水平造成不利影响。

The number of microorganisms in the downflow chamber was bigger than those in the upflow one. suggesting that downflow chamber had very important function during wastewater treatment.

构建湿地基质微生物数量与污水中的KN以及COD〓的去除率存在显著相关性，说明基质微生物的活动是它们去除的主要途径。

Hence,in this study, the change of soil microbial communities were investigated through direct current field ,which is supposed of provide a theory basis for soil electrokinetic bioremediation technology.

而电场作用下土壤微生物群落的变化与利用电场生物修复效率密切相关，本文鉴此研究了直流电场作用下对土壤微生物群落多样性的变化规律，以期为电动生物修复技术的应用提供了一定的科学理论依据。

Using the relativity between potential ennoblement and bacteria activity, we found that the higher temperature of seawater increased the activity of bacteria.

海水盐度的增加和减少都会降低微生物的活性，对微生物膜的附着起到一定的阻碍作用。

And soil porosity, nutrient, microbe quantity, microbial biomass and enzyme activity showed the trend of rise along with the increase of exclosure period, and after exclosed for 12 year, the quality of the soil reached to the best.

且随围封年限的延长，土壤孔隙度、土壤养分、微生物数量、微生物生物量及酶活性呈增加的变化趋势，围封12年土壤质量最好。

2After the utilization of seasonal exclosure, the proportion of coarse sand (2.00～0.25 mm) dropped significantly, and the proportion of fine sand (0.25～0.05mm) and silt and clay (.05mm) increased significantly, soil bulk density and compaction dropped, soil porosity, nutrient and microbe quantity increased, soil microbial biomass and enzyme activity enhanced in the layer of 0～10cm and 10～20cm.

2放牧草地采用生长季围封恢复措施后，土壤0～10cm、10～20cm土层中粗沙(2.00～0.25 mm)含量显著降低，细沙(0.25～0.05mm)和粉粘粒(。05mm)含量显著增加，土壤容重和紧实度降低，土壤孔隙度、养分含量、微生物数量、微生物生物量碳、氮含量增加，土壤酶活性增强。

The bacteria amounts on metal surface increased according to an exponential law and its adsorption kinetics at metal surface was proposed.

给出了微生物附着的动力学方程，并对其进行了讨论。两种钝态金属开路电位的变化和其表面微生物数量增加有着相似的趋势。

Based on a long-term experiment, the soil organic carbon, readily oxidizable carbon and microbial biomass carbon of two sequence rotation systems with spring wheat and field pea in soil layer under different tillage patterns were studied.

以长期定位试验为基础，对麦－豆轮作次序下不同耕作措施间的土壤有机碳、易氧化碳以及微生物生物量碳进行了测定，计算了土壤微生物商在各个序列中变化并对土壤各级有机碳库进行了相关分析。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
