用远藤营养纸垫滤膜法对天津等地8类水源、36个水样进行了水中大肠菌群的检验。实验结果说明,远藤营养纸垫滤膜法对正常未受损伤的大肠杆菌群检出结果与国标品红亚硫酸钠滤膜法一致。而对天然水和自来水中大肠菌群的检验,结果基本上均高于国标品红亚硫酸钠滤膜法和多管发酵法。改进的远藤培养基对受到诸如冷、热、紫外线、氯消毒等因素致损伤的大肠菌群细菌有促进其修复和生长的作用,从而提高了检出效果和饮水的安全程度。
With Endo nutrition paper pad filter membrane method in Tianjin and other 8 types of water, 36 water samples were tested for coliform bacteria in water. Experimental results show that Endo nutrition paper pad filter membrane method for normal intact E. coli colony detection results with the national standard mahogany sodium filter method. The natural water and tap water in the coliform test, the results are basically higher than the national standard mashine filter membrane method and multi-tube fermentation. The improved endotrophic medium can promote the repair and growth of coliform bacteria which are damaged by factors such as cold, heat, ultraviolet light and chlorine disinfection, thereby improving the detection effect and the safety of drinking water.
