The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.

试验稚鳖池水中共分离出21株异养细菌，其中优势菌为假单胞杆菌属细菌；底泥中共分离出25株异养细菌，其中优势菌为芽胞杆菌属细菌，微球菌属细菌假单胞菌属细菌，三种自养细菌分别为具有氧化硫化氢、元素硫或硫化亚铁的硫细菌；具有氧化氨为亚硝酸的亚硝化细菌和能将亚硝酸进一步转化成硝酸的硝化细菌。

The population distribution of physiological groups of bacteria,including ammonifying bacteria, denitrifying bacteria, nitrobacteria and nitroso bacteria, organic phosphate dissolving bacteria and inorganic phosphate dissolving bacteria in water body and sediment of Suzhou Creek are studied with MPN and flat account method from Jan. 2002 to Mar. 2003. The role of these physiological groups of bacteria in Suzhou Creek aquatic ecosystem is discussed.

用最大可能数法和平板计数法，于2002年1月～2003年3月对苏州河水体和底泥中的主要微生物功能菌群——包括有机磷分解菌、无机磷分解菌、氨化菌、亚硝化菌、硝化菌和反硝化菌等进行了生态调查，并分析探讨了它们在苏州河水生态系统中的作用。

According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.

通过以上试验内容研究发现，SUFR 系统中的微型动物种群较多，微生物生态系统稳定；系统中微生物的数量与营养盐的含量密切相关，其中总异养菌与COD的相关系数r 为0.949，有机磷细菌与TP 的相关系数r 为0.815，亚硝化菌与NH4+-N的相关系数r 为0.909，反硝化菌的数量和TN 的相关系数r 为0.653；污水生物除磷工艺中进水COD 的浓度、DO 浓度、泥龄的长短、温度都是影响聚磷菌释磷及吸磷效果的不可忽视的因素；SUFR 系统中的磷细菌呈现种群多样化的趋势，没有占绝对优势数量的磷细菌；微孔滤膜近自然培养法是对传统纯培养技术和富集培养技术的有力补充；整个SUFR 反应器系统中污泥的生物活性很好，就可生化性来讲，厌氧反应器大于缺氧反应器大于好氧反应器；按照动力学方程式求出的细胞生长动力学特征值和SUFR 脱氮除磷系统工艺的实测值结果基本吻合。

bacteria：细菌

郭嵩焘于6月份在英国医学院第一次听到"细菌"(bacteria)这个词,明白意思后,他苦思冥想翻译成了"太空中尘埃野马".

bacteria：域: 细菌域

微生物包 木耳 灵芝)所以微生物不一定是看不见的. 细菌包括球菌 杆菌 螺旋菌 弧菌,细菌是单细胞的原核生物,域: 细菌域(Bacteria) 门: 变形菌门(Proteobacteria) 纲:γ-变形菌纲(Gammaproteobacteria

bacteria：细菌类

培养细菌类(Bacteria)武器的原理,大致上跟酿酒大同小异:将冷冻保存的「细菌种子」放入发酵锅(Fermenter)内繁殖,细菌便会以几何级数的速度生长,在很短时间就可以繁殖出大量细菌.

bacteria：真细菌

按照现行的生物系统发育(Phylogeny)关系(与1987年之前的分类系统不同;2层下段),可将这些物种分为3个域,即真细菌(Bacteria)、古细菌(Archaea)和真核生物(Eucarya).

Anaerobic bacteria：厌氧性细菌

"厌氧性细菌"(Anaerobic Bacteria)就是不需要氧气也能生存的细菌,所以"厌氧性细菌"(Anaerobic Bacteria)是可以在无氧环境的密封式过滤系统中、砂床中及一些较少量氧气的地方生存.
