1992年美国标准方法委员会在第18版(1992年10月出版)《水与废水检验标准方法》中正式推荐一种新的检测饮用水中大肠菌群的方法,英文称为Chromogenic Substrate Coliform Test”现译为“大肠菌群产色基质试验”。该技术最早用于分析某些微生物细胞内的结构酶以鉴定这些微生物。它是将一种可被微生物水解的基质作为待测微生物(靶微生物)的特定基质(这些特定基质也称之为指示营养物,即具有指示剂和营养物两者的作用)。在靶微生
1992 American Standard Methods Committee formally recommended a new method for the detection of coliforms in drinking water in the 18th edition (October 1992) “Standard Methods for the Examination of Water and Wastewater”, known in English as Chromogenic Substrate Coliform Test “ Is translated as ”coliform bacteria chromogenic substrate test." The technology was first used to analyze the structure of enzymes in certain microbial cells to identify these microorganisms.It is a microbial hydrolysis of the substrate can be used as micro-organisms (target microorganisms ) Of these particular substrates (these particular substrates are also referred to as being indicative of nutrients, ie, having both an indicator and a nutrient.) In the target microorganism
