摘要: The present invention provides a method which is specific to determining and is capable of enumerating Escherichia coli ( E. coli ) in a sample water or sewage specimen. The method comprises adding to a cultured specimen a chromogenic reagent which when subjected to in situ E. coli β-glucuronidase activity produces clearly defined vivid colourization of any individual colonies deriver from E. coli cells in the test specimen.
