查询词典 nitric bacteria

The high inoculum levels increased the bacterial growth and shorten the time for antifungal substance production. The powder of rice, soybean cake, yeast, and wheat bran, CaCO3 and KH2PO4 were better nutrients for the bacteria growth and antifungal substance production. There were two stages during the fermentation process at 30℃. The growth of bacteria increased at the first 24 h and the pH of broth rose, but no antifungal activity was observed until 41 h later and reached to the highest level at 114 h.

基本营养物质的初步筛选试验证明：大米粉、豆饼粉、麦麸、酵母粉和CaCO3及KH2PO4是发酵培养基中最佳的营养物质，可满足抗菌物质产生对碳、氮和矿物质的营养需求。B-903的发酵过程可分为两个阶段：在30℃下，24小时内，细菌数量达最大值，pH值由低向高变化，但此阶段检测不出抗菌物质的活性；第二阶段，培养41小时后，抗菌物质活性开始显露，至112小时后达最大值，pH值也逐渐由高变低。

The sludge in SBMBR1 presented granular characteristics and settled very well. The sludge in SBMBR1was brown and the sludge flocs was smashed by the shear force due to high intensity of aeration. The sludge size decreased and the sludge flocs blended with water forming ropy solutions, and there was no distinguish interface between water and sludge. Low sludge age and high loading operation enabled the sludge in SBMBR1 keeping higher sludge activity and the MLVSS/MLSS ratio and SOUR values of SBMBR1 were higher than SBMBR2. Both in SBMBR1 and SBMBR2, there were large amount of zoogloea, bacillus, coryneform of bacteria, and pediococcus. However, in SBMBR1 there were also a lot of Protozoa like epistylis and etc. A certain amount of filamentous bacteria can also be found in SBMBR1. The biological species in SBMBR1 were much more abundant than that in SBMBR2.3. Membrane fouling on flat-sheets membrane was observed and analyzed with AFM, SEM and TEM. After the measurement of membrane surface EPS and membrane surface ETX analysis, the pollutants composition on the surface of flat-sheets membrane was calculated.

从外观观察SBMBR1反应器中的活性污泥呈浅黄色，随着运行时间的增加，污泥粒径逐步增加，SV、SVI值逐步下降，呈现出较强的颗粒特征，沉降性能良好；SBMBR2污泥呈土黄色，污泥絮体被高强度的曝气所产生的切应力所打碎，污泥粒径迅速降低，絮体较为细碎，和水相混合成均一粘稠的溶液，看不到泥水分界面；低泥龄、高负荷运行，使得SBMBR1可以保持较高的微生物活性，MLVSS/MLSS值、SOUR值均高于SBMBR2；两级反应器活性污泥中均有大量的菌胶团，长杆菌、短杆菌和球菌是构成主体，但SBMBR1活性污泥中含有大量固着型原生动物如累枝虫等，还存在着一定数量的丝状菌，生物相要比SBMBR2丰富。3、借助原子力显微镜、扫描电镜、透射电镜等手段对平板膜污染现象进行观测和分析，并通过膜表面污染物EPS测定、污染膜表面能谱分析，得出平板膜表面污染物的组成。
