细菌抑制

A submerged membrane sequencing batch bioreactor was used to treat coke wastewater.Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).Long sludge retention time may result in the accumulation of metabolic products and high molecular materials,and thus inhibiting activity of nitrate bacteria and causing a ccumulation of NO2-,which is beneficial to the running of short-cut denitrif ication.However,too long retention time will affect the activity of nitrite bacteria,detrimental to the treatment effect of ammonia nitrogen.

采用浸没式膜生物反应器处理焦化废水的试验结果表明：膜的截留作用可使硝化菌在反应器内富集而有利于提高系统的硝化能力，其去除氨氮的最高负荷为0.19kg/(m3·d)，出水氨氮＜1mg/L(去除率为99%)；泥龄长可能使微生物的代谢产物或其他大分子物质积累，从而抑制硝酸盐细菌的活性，导致NO2-积累而有利于短程脱氮的进行，但泥龄过长也会影响亚硝酸盐细菌的活性，从而影响对氨氮的处理效果。

The results showed that the main pathogenic bacteria ledlocal cows to endometritis were streptococcus,the next,Escherichia coli,staphylococcus and pseudomonas aeruginosa.NFPL could quickly reduce thenumber of the bacteria in uterus,and strongerly inhibit these bacteria in vitro.NFPL could excit the uterus,which occurred in enlarging contractionamplitude.NFPL could lower abnormal high content of progesterone and raiseabnormal low oestradiol.

结果表明，引起本地奶牛子宫内膜炎的主要致病菌是链球菌，其次是大肠埃希氏杆菌，葡萄球菌，绿脓杆菌；新促孕液能能迅速减少病牛子宫内细菌的数量，在体外对这些细菌也有较强的抑制作用；新促孕液对兔子宫有明显的兴奋性作用，主要表现在收缩波幅的加大；新促孕液能降低病牛血清异常升高的孕酮含量，升高异常降低的雌二醇含量。

As the aging temperature increases they evolve into rodlike and keep certain orientation relationship with the ferrite matrix.

在抗菌不锈钢抗菌过程的前期，抗菌性能表现为对细菌生长和繁殖的抑制，后期表现为对细菌的杀灭。

Results Based on the analysis of the number and lightness of DGGE bands, we studied the change of the microbial community diversity activation of stratal bacteria.

通过对内源微生物激活前后DGGE条带的数量和亮度变化分析表明，油藏环境中的细菌在种类和数量上并不丰富，激活剂的加入改变了菌群原有的贫营养环境，从而使一些因营养缺乏生长受抑制细菌得以大量繁殖，菌群结

From its the depart in splanchnic organization arrives bacterium of 2 individual plant, pass bacteriological method appraisal, one individual plant is deputy pig bloodsucking bacili, another individual plant is a pig streptococcic; will send check sample book have an inoculation to marc-145 cell, can observe cellular pathological changes, the pcr of virus fluid classics of results detects, for positive of blue ear ill viru

从其内脏组织中分离到2株细菌，通过细菌学方法鉴定，一株为副猪嗜血杆菌，另一株为猪链球菌；将送检样本接种到marc-145细胞，能观察到细胞病变，收获的病毒液经pcr检测，为蓝耳病病毒阳性；将送检的样本接种spf鸡胚，收获的鸡胚尿囊液有血凝性，血凝试验和血凝抑制试验鉴定为猪副黏病毒。

For the first time a safety and nontoxic solvent were used to gain the crystal of teasaponins,avoiding environmental contaminated of toxical impregnate and receiving the high purity teasaponin products.

茶皂素粗提物对食品腐败细菌、真菌以及植物病原真菌的抗菌实验结果表明，茶皂素对各种细菌和真菌均有不同程度的抑制作用，且抑菌效果与茶皂素浓度呈正相关。

Methods: The interference evaluation experiment proves that IVIG exerts strong inhibitions in Bacterial Endotorxin Test. While the interfering factors can't be eliminated by treatments such as dilution and neutralisation, they are liable to be inhibited provided that the IVIG samples are to be diluted by 1:4 with the Dilution Solution Ⅰ.The BET for IVIG preparation diluted by 1:4 with the Dilution Solution Ⅰ is carried out comply with the Chinese Pharmacopoeia(2000 Edition) The lysate with sensitivity of 0.125Eu/ml is used in the test,and the results of the BET are comparable to that of Pyrogen Test carried out in rabbits.

通过干扰评价实验证明IVIG对细菌内毒素检查法有强烈的抑制作用，单纯用简单稀释和调整pH值法无法消除干扰，如果用稀释剂对IVIG作1：4以上的稀释，即可消除样品对该检查法的干扰，利用灵敏度为0.125EU/ml的鲎试剂，将样品用稀释剂稀释4倍，按中国药典（2000版）进行细菌内毒素的检查，结果与家兔热原质试验进行比较。
