This article illuminated the significance of fecal coliforms detection in drinking water , and emphasized the relationship between coliforms and fecal coliforms and summarized the conditions for fecal coliforms detection 摘要阐述了在饮用水中检测“类型大肠菌群”的意义，强调了大肠菌群与类型大肠菌群的关系，总结出“类型大肠菌群”的检测条件。
However , the receptor and translocation domains of the colicin ia can only recognize the inner and outer membrane receptors of the escherichia coli , therefore the wild type colicin ia can not be developed into antibiotics against other types of bacteria 然而由于其信号识别结构域只能识别大肠杆菌外膜和内膜上的特异受体，因此野生型大肠菌素难以拓展成为对抗它种细菌的抗菌素。
Experiment and research on influence factors of wastewater treatment by ultraviolet disinfection , and come to conclusion that relations of radition intensity , turbidity , radition time , water thickness and total coleocele livability 摘要探讨了紫外线消毒在污水处理中的影响因素，并得到了辐射强度、浊度、水层厚度、辐射强度和辐射时间与总大肠菌群存活率之间的关系，为消毒器的设计提供依据。
They are sulphide and free hydrogen sulphide . from 1989 , selected monitoring stations also monitored e . coli and faecal coliforms , which indicate faecal contamination from domestic sewage and animal waste . these two bacterial parameters were extended to all stations from 1999 自1989年开始，部分河溪监测站开始监测大肠杆菌及粪大肠菌群以显示住宅污水及动物粪便所造成的水污染其后在1999年起，所有监测站均测试此两项细菌参数。
Coli of the stored fecal increased 3 . 9 10 - 3 , and the rate of died ascaris eggs reached to more than 96 % . [ conclusion ] after one - year application period , the sanitary indexes of the stored fecal in service fecal pit and storage fecal pit could both meet the sanitary standard of non - hazardous treatment of fecal 双坑交替式早厕是由使用坑和封存坑组成的通风式农村户厕，粪便封存坑封存四个半月后，粪大肠菌值可提高3 9 10 - 3 ，蛔虫卵死亡率达96以上。
Monitoring of 3 bathing beaches showed that the water at feishatan beach and jinhuantan beach was in very good condition and the number of days suitable for people swimming had reached 90 % but that the water at lingjiaozui bathing beach in jida was found to contain fecal coliform over and above the prescribed standards and was therefore unsuitable for bathing activities 而对飞沙滩等三处海水浴场水质的监测结果表明,飞沙滩和金还滩水质基本为优,全年适宜游泳的天数达到90 % ,吉大菱角嘴海滨泳场的粪大肠菌群超标,人体不适宜直接接触。
Abstract : the hygienic condition of food - wrapping paper directly concerns the quality and safety of the wrapped food . thus , a sample investigation was made on the wrapping paper of 60 candy , pastry and ice - cream shops and that of food stalls of xinxiang city . the result shows that the hygienic qualification rate of the food - wrapping paper on the present market is only 72 . 7 % . furthermore , the contents of lead , arsenic and bacterium coli are rather high . this should be taken seriously by the parties concerned 文摘:食品包装用纸卫生与否，直接关系到被包装食品的卫生质量和安全.鉴于此，对新乡市60家糖果、糕点、冰糕店及街头食品摊点所使用包装用纸进行了抽样调查.结果显示，目前市面上食品包装用纸的卫生合格率仅为72 . 7 % ，且部分食品包装用纸中铅、砷以及大肠菌群等含量均存在严重问题，需引起有关方面的?重视
This paper analyses the results of supervison on 1293 tablewears in 176 catering trades in xining city from 1995 to 1997 in order to discover the effect of tablewear sterilization . the result shows that the qualified - rate of the testing germs on the surfaces of tablewears reduced year by year . after analysing and comparing with the results of other disinfecting methods , we find it is very important that correct and effect methods must be choiced in tablewears sterilization . in addition , to prevent second contamination , keeping the sterilized tablewears clean are very important , too . also some solutions is put forward in the paper , which is about how to strathen the management of tablewears disinfection 为了解西宁地区的饮食业餐饮具消毒工作的状况，分析餐饮具消毒效果，于1995 1997年用大肠菌群快速纸片法对市区176家饮食业店的1293份餐饮具进行消毒效果监测，结果表明，消毒后餐饮具进行细菌检测合格率总体水平不高，经对几种消毒方法的消毒效果进行分析比较，明确了餐饮具消毒工作应选用正确有效的消毒方法和消毒后的餐饮具应采取保洁措施，防止餐饮具二次污染的重要性，并提出加强餐饮具消毒工作管理及监测的一些对策。
The fusion protein was bactericidal active against staphylococcus aureus . in present study , we will truncate the none channel - forming do main , then attach the agrd to the pore - forming region ( k544 - i626 ) to construct a new engineered multidqmain protein machine - compact engineered peptide targeting staphylococcus aureus . such engineered peptide was constructed by linking the gene of staphylococcal agrd pheromone with the gene of c - terminal ( 1626 ) of colicin la pore - forming region ( k544 - i626 ) with site - directed mutation 利用点突变方法将金黄色葡萄球菌信息素agrd ( i型， ystcdfim )的基因引入到大肠菌素fa梭基端1626基因上，并将限制性内切酶sacl酶切位点基因分别引入到大肠菌素fa的p4和k544上，通过酶切、胶回收、连接获得含大肠菌素ia水性孔道结构域和金黄色葡萄球菌信息素agrd基因的重组质粒。
In the 1990s , the pheromones of gram - positive bacteria , which regulates the growth and toxin secretion of the same type bacteria , were identified they were peptides consisted by dozens of amino acids . the pheromones can auto - recognize membrane receptor of the identical types of bacteria . we had constructed a fusion protein named pheromonicin by introducing a staphylococcal pheromone agrd at the c - terminal of the colicin ia 丘小庆等利用信息素的自主导向特性和大肠菌素ia的致死性通道特性构建了由金黄色葡萄球菌信息素agrd和大肠菌素ia组成的融合蛋白，命名为pheromonicin ，该蛋白表现出了信息素和大肠菌素ia都不具有的抗金黄色葡萄球菌活性。
